CW Radius lasers are full-featured, high-performance, CW diode laser systems that include a laser head, power supply and optional control box. Designed for convenient mounting into a HeNe laser holder for fast and simple integration, they deliver power, stability and performance in a complete package with the best value. Adjustable Focus Radius lasers allow faster and easier system integration. When optimizing the beam for best focus or fiber launch, the adjustable focus eliminates the need for an expensive beam expander. Instead, a tool (included) adjusts the beam divergence through the front shutter port. The optional control box (included)—with a key-switch, 5-second power-on delay, emission indicator and interlock— allows the system to comply with CDRH safety regulations. The control box plugs into the side port of the Radius. The side port can also be used to modulate the laser on-and-off as fast as 100 Hz through the interlock control input. This modulation can be used to extend the lifetime of the diode by enabling the laser to be ‘on’ only when needed—while the thermal system remains constant for improved stability.

Mounted on a large TEC, the diode laser and optics remain at a constant temperature of 22°C. A heat sink with an internal fan removes the heat. The closed-loop, constant temperature keeps the wavelength constant, minimizes mode-hops and maintains power stability.

This compact, solid-state laser offer a complete CDRH solution with the laser head, control box, and power supply included. Laser head has a HeNe style packaging that with a similar diameter that can easily be implemented into existing systems; but with a much shorter length than a similar powered HeNe laser. Mounted on a TEC, a heat sink keeps the temperature and wavelength constant, as well as maintaining beam and power stability. Model features adjustable beam focus and collimation, a large TEC with bipolar linear drive, internal cooling fan with vibration-elimination mounting, multi-layer ESD shielding, and a convenient back panel on-off switch with power LED indicator.

This is another fantastic laser on offer at a very cheap price, which cost almost £3000 new. It is surplus to requirements and is a fantastic piece of equipment. Comes with instruction manual, power pack, control box and the laser itself. No obvious wear or tear.
