much better than sku.46390 – 2~5mW Dot Red Laser Module (5-Pack/3V) Reviews

posted by linoleo on 03/25/2013 Certified Owner

Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

Pros:
- more solidly built than sku.46390 - much brighter than sku.46390 - appears to have constant current driver: two transistors are visible on the PCB, and my samples pull a constant ~20mA from 2.5V to 5V
Cons:
- larger diameter than sku.46390 - no adjustable focus (but well focused as is) - spot is elongated
Other:
After bad experience with sky.46390, I was pleasantly surprised - these modules are excellent value for money.
Bottomline:
If you're looking for small laser modules, these are the smallest ones of good quality at DX. Will order more.
