Search for equivalent 650nm, 3.3mm OD laser module

$
0
0
I am currently using a less than 1 mW, 650nm, 3.3mm OD x 7mm, 3.3V (max) laser module in a design for a medical device to perform a simple pointing/locating task. It is in a plastic case and was perfect for the location and application but unfortunately, it does not meet critical temperature specifications. The part is the APCD-650-17-C2-A from Arima Lasers and it is also sold by Laser Components with a different part number. The part has a storage temperature range from 0C to 60C and my requirement is -25C to 70C.

My search has included many laser manufacturers and resellers but the only other companies that I have found to date that have anything close are:
  • Laser Components/Arima
  • Egismos
  • ROITHNER LASERTECHNIK GmbH
  • Frankfurt Laser

Egismos has one module that meets the temperature requirement but is 4mm OD x 10mm. The smaller size of the Arima part is critical to the design and we do not think we can do enough redesign of the package to make the larger module fit.

My question for the group is, what other companies might have small laser modules that meet or exceed this requirement set (<1mW, 650nm, 3.3mm OD x 7mm, 3.3V (max), storage temp -25C to 70C, plastic case preferred)?

And a sub question: Other than Google searches, what other sites might I check out to try to ensure that I have done an exhaustive search of the available products/manufacturers?

I did do several LPF searches but possibly I did not use the correct search terms to find the information.

Thank you in advance for any and all replies!

I am desperately trying to find out about how to rewire my exciter be used again with an original 164 tube. IT was reconfigured for a Lexel tube I guess Lexel before being bought out by Cambridge lasers made a replacement tube for the 164 argon head. I would like to rewire it for the original tube. Please someone help. thanks Tom

Questions about a 400mw 532nm laser pointer

Hello, I want to buy a 532nm green ebay laser for $99. I asked the seller for the power output and he said that it is 400mw laser, he even sent a picture of it being measured on a power meter. Here's the link to the laser:

Green Laser Pointer Pen Torch 532nm High Power Burning Beam 1*18650 & Charger | eBay

Should I trust this seller? Is that a good price for a laser of that power? And how bright is a 400mw 532nm laser, compared to lets say a 1000mw 445nm laser.
I know all the safety precautions, thank you. :)

Link to the laser - 10 Miles 532nm 5mw 303 Green Laser Pointer Lazer Pen Beam Light +2*18650+Charger | eBay

Hey this is my first review, first off I highly recommend this laser. It is definitely overspec, so make sure you get safety glasses! It is not a burning laser though, so do not expect it to do that. These are the glasses I have for now until my Eagle Pair arrives, they are perfect for this laser. Laser Safety glasses goggles 190nm-540nm(green/purple/blue) USA Seller | eBay

Before I get started, no fog was used to bring out the beam. Anyways, time to review this! Here is a picture of the device itself, warning lable aswell. The label claims 1mw to pass customs (not sure why he didn't just put 5mw like on ebay because that still would have got past customs, whatever though :P) Don't have an LPM to measure it's wattage, so if anyone ends up purchasing this laser with a LPM let me know I'm curious haha!





This package came with a charger and 2 18650 batteries aswell. The batteries are pretty good, much better than what you'd expect! Make sure to put the negative end in, positive facing up. The charger is your average charger, nothing special but it will charge the batteries if you don't have something better.



The beam is actually pretty visible in a lit room! Even more so than the picture below. The spot is very bright, not enough to instantly damage your eyes, but it's not something you want to look at for more than a second.



And finally here are some images in a dark room. Beam is more visible than it is in the camera. Doesn't help that I used my phone lol. Can be seen from the side very easily.











That's all for now! I highly recommend picking up this laser if your looking for a green laser. It's not really going to burn anything, (maybe pop a balloon, didn't have one on hand unfortunately.) It does not come with a focusable lens, it is always the same. If a focusable lens were attached it may gain burning capabilities. The laser arrived very quickly, on the 3rd day after ordering.

What's the difference between these lasers

Laser and laser glasses testing and interesting results

$

Just thought I'd share some testing I did tonight with a few pairs of safety glasses and two different green lasers.

I'm testing using a ThorLabs benchtop power meter with photodiode sensor.

I have a green laser pointer that I got years ago. Fairly bright but never tested before. I also have a green laser pointer that my father-in-law just bought on-line. It seemed really bright to me so I decided to do some testing.

I have some HDE or HDE clone glasses that I just got with an eBay 1W 450nm laser and a pair of Uvex SCT-Orange glasses (which are not rated or certified as laser safety glasses but have been tested to perform well).

I got some interesting results...

Old pointer:

25mW raw - 103pW with Uvex glasses - 46pW with HDE glasses

Father-in-Law's pointer:

205mW raw - 150mW with Uvex glasses - 115mW with HDE glasses

I found this rather interesting. Both the HDE and the Uvex glasses seem to do well at 532nm with the 25mW laser (note those values through the glasses are pico Watts). However the 200mW (!!!) laser is another story. The result has me wondering if that laser is putting out a ton of IR or the glasses simply can't cope at that power level. It seems like it would be an awful lot of IR but...

Going to do more testing but I thought I'd share and get everyone's thoughts as well.

1 kW Laser

I was thinking of saving up for a 1 kW laser rifle much like the one styropyro built in his video once I get my student loan paid off. What I would do differently would be to use NUBM44s focused independently with a G-2 lens', then much like styropyros to collimate them into one with a large lens at the end. I think driving them and focusing them independently would create a much better beam spot but would also cause a great deal of heat. I think a noble design could fix that easily though. I think it would cost me around $20k to do this but it would be absolutely insane. Some of you may think I've lost my mind but wouldn't that be a sight man, like to see a kilowatt of laser energy in a beam the diameter of a hair in a handheld device :beer:

What is the main cause of power drop off ?

What is the main cause of power output drop off bellow 60 seconds run time ?

assuming it's not batteries draining down.....

Is the diode getting hot ?

Is it something to do with the driver ?

I guess it has to do with one of the two because what else is there ?

Image with ScannerMax C-506.
In height (Y) all correct, but in width (X) very narrow.

I have checked connections and I do not see anything strange.
I send you the picture in case you can help.







It is normal to have current continuity between GROUND (X), GROUND (Y), GROUND Stanwax board, aluminum base (where power supplies, galvanometer and amplifiers are screwed) and GND house (240v)???

Can this be the problem of narrow image in channel X?





Have a happy weekend!

Scientists have transformed the harmless mouse into a killing machine with the flip of a switch, using lasers to manipulate the rodent’s brain circuit and turn on their predatory instinct.
Mice, which usually serve as prey for larger mammals, became threatening predators when researchers used a laser light to activate two sets of neurons in the amygdala – the area of the brain involved in emotions, behavior and motivation.....

Battery Safety Concerns

Hello,

I recently acquired a new Nitecore "Intellicharger NEW i2" to charge my AW IMR 18350 batteries. As I was reading the Nitecore user manual, I came across a warning that reads "Do not use a 4.2V/4.3V Lithium battery when its voltage is lower than 2.8V, otherwise it can be over-discharged, and/or prone to explosion at next charging."

How will I know when my batteries have reached this voltage? Will my laser stop working at this point?

I'm sorry if this is a n00b question or in the wrong forum. I tried searching for a thread that discussed this issue but was unable to find one. Thanks in advance for your help!

Hi everyone, I'm new to lasers literally just bought a 1-watt blue laser only to find it breaks the next day literally being turned on for 5 seconds and pops. I'm in the UK and looking for a really good laser I've got a budget of £250 can anyone recommend me some sites? What's the big dislike about wicked lasers as well aren't they really powerful.

LGI-101 Copper Vapour Laser System

Before I had made my "homebuilt CVL system" I had a chance to play with the commercial russian CVL called LGI-101. I had found it in the University laser lab NOS in unpacked factory crates. The lab didn't use it for anything since buying it in 1989. It is a first-generation CVL with only 3W of rated power on both 510 and 578 nm lines, despite the large size of the laser head and tube. The laser tube and the head were in separate wooden crates, the power unit stood nearby. After putiing it all together I got very bright laser beam, which burns wood slowly even in unfocused condition, because its diameter is relatively small -- 12 mm. Unlike the UL-102 tube, the LGI-101 one is in full glass envelope, much smaller in diameter but nearly twice longer than UL102. Thermal insulation is worse than in UL102, so it requires much more input electric power for the same output as UL102, electrical efficiency is lower.

The power unit is a big cabinet made of metal and devided in four sections, containing HVDC source with the 3-phase HV transformer, variac voltage regulator, which consists of 3 variacs сoupled with plastic gears, master oscillator and trigger circuit for the thyratron, and main thyratron pulse circuit. The thyratron in it is the biggest I've ever seen in person -- 25 cm tall and 15 cm in diameter, with water cooling. Some our local Tesla coilers would just drool when seeing this cabinet full of high voltage, which weighs nearly a half of ton. :drool:

Anyway, despite some drowbacks this laser works great!

Unfortunately I was not allowed to move it to my laser collection at my home:yabbmad::yabbmad:

All pictures won't fit one post, so I'll make a couple of them.
