TTL Laser Retail
Cost: $19.95 each
Description: This is the basic laser card module with circuitry built in so that it can be turned on/off with a TTL signal. Includes polarized Molex connector to prevent reverse connection. On-board voltage regulator accepts 5-12VDC. A customer tested these units on his Agilent optical analyzer (Thanks Trenton!). The wavelengths were 654.5 nm +/- 0.5 nm at 70 degrees F for the 4 lasers tested.
