    234B Series TEC TO-Can LaserMount User’s Manual · Page 3 Introduction Thank you for choosing the 234B TEC TO-Can LaserMount from Arroyo Instruments. The 234B LaserMount is designed for high performance and long term use. The 234B LaserMount is a higher performance TO-can mount, similar to our smaller 224 LaserMount, but offering a much higher thermal capacity (up to 10W at 25°C), lower operating temperatures, and a much higher 3A higher laser current capacity.
