RO Series
Collimated Single Frequency Laser Modules
Ondax’s RO Series Single Frequency Collimated Laser Module
integrates our SureLock™ wavelength-stabilized lasers with active
TEC cooling and precision current control circuitry into a compact,
cylindrical package. Designed for easy mounting and integration,
this rugged self-contained module is ideal for incorporation into
precision instrumentation or for laboratory applications. The built-in
temperature controller maintains the laser diode temperature within
±0.01°C, resulting in excellent power stability that varies less than 1%
over the long term.
