Coating Linearity (White Uncoated TECs)

I thought I'd share this finding...

We were doing some Coating Linearity tests yesterday
using the new Digital Adjustable Laser Power Supply
I had built for the shop in my other Thread.

I decided to do a quick test of some Uncoated White
TECs to see if they were Wavelength Broadband and
Power linear.

Here are some basic results I got at 1000 mW :-

White Uncoated TEC

808nm - 1000mW
520nm - 1062mw
450nm - 1184mW

As a comparison here is our AX3 coating at 1000mW :-

LaserBee AX3 Coated TEC

808nm - 1000mW
520nm - 1008mW
450nm - 1010mW
