The 222 TEC TO-Can LaserMount provides active TEC cooling for TO-3.8 lasers. The device is inserted into a socket and clamped to the cold plate by a machined aluminum bracket. The 222 is designed for post-mounting (post-mount not included), with 8-32 and M4 threaded holes on the bottom of the mount.
Precise Cooling Control
The 222 LaserMount integrates a Peltier module for precise control of the package temperature. With a +15°C to 85°C operating range, the 222 LaserMount covers a wide range of temperature control needs.
CAGE and Lens Tube Systems
The 222 directly supports 30mm cage systems, with or without the standard cover installed. Looking to integrate 1″ lens tube optics? Add the 224-C-02 Opto-Mech Cover, which adds support for 1″ lens tube systems and also supports 30mm cage systems.
A cover plate is included to minimize the impact of air thermal gradients on the temperature of the device. A nitrogen purge nipple on the rear of the mount can be used to prevent condensation when operating below the dew point. A 4mm banana jack provides a convenient wrist strap connector or can be used to ground the mount to an optical table.
DB-9 & DB-15 Interfaces
The laser driver and temperature controller connections are made through a DB-9 LDD and a DB-15 TEC connector on the back of the mount, which allows for quick connections to any Arroyo Instruments controllers.
Thermistor Control
The mount uses a 10K thermistor for temperature feedback. More details on working with thermistors can be found here.
