** Operation temperature means within this temperature range, the laser spot/line will not be affected to change the spot size/line width. It can still work over this range, but the laser spot size or laser line width will be larger.

It’s simple: to help you save money. Lenses with adhesive backing typically cost twice as much because of the extra time required to pre-laminate the adhesive. Even with the backing, you’ll still need to complete the second half lamination process yourself. So, why not do it all at once and save on costs? You can easily find high-quality double-sided adhesive on Amazon by searching for "double-sided adhesive sheet 3M."

The Laser output power must be stable especially in safety reason. But the Laser power is related to the Junction Temperature (Tj) of the LD. It means that as the different Tj, the Laser power will be increased or decreased. An APC (automatic power control) circuit is used to compensate the varying Laser output power to constant. As shown in the picture, The principle of the APC circuit is monitoring portion of the laser light from the LD by the built-in PD and real-time feedback to control the laser output power constant and safety.
