Now Available in 633 nm
Coherent’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. The NEW RO-USB Series incorporates a USB interface to add remote current and temperature control.
The RO Module is NOW AVAILABLE IN 633 nm and in wavelengths up to 808 nm to suit any application.
