iChrome CLE
Compact, efficient four-color laser engine
• Four colors in one box • 405, 488, 561, 640 nm with > 20 mW each • COOLAC automatic alignment
• Unique modulation capabilities • Unified user interface
TOPTICA's iChrome CLE is a compact laser engine that combines four laser lines in one box. All integrated colors are provided via one polarization-maintaining single-mode fiber. It is available with 405, 488, 561 and 640 nm and more than 20 mW guaranteed output power after the fiber each. The system guarantees a plug & play installation since it includes TOPTICA's proprietary COOLAC automatic alignment technology.
This way the laser combiner system is ready-to-use after one simple button click. 561 nm laser light is generated by TOPTICA´s proprietary FDDL technology. Each laser line, including the 561nm FDDL, can be directly modulated up to a frequency of 1 MHz and TOPTICA's "Complete OFF" mechanism guarantees zero photons in the "off"-state.
Options
Standard Features:
• COOLAC: Constant Optical Output Level by push-button auto-recalibration. This feature ensures full drop-shipment capability and best stability even under heavily changing ambient conditions
• FINE: Feedback Induced Noise Eraser for laser diode based wavelengths. Immunization to optical feedback, ideal for fiber coupling and reflective surfaces
Optional Features:
• FiberOut: Fiber collimator for FC/APC and FC/PC fibers
