Coherent has introduced two bioinstrumentation lasers that deliver high power in a compact package.
The Sapphire 488 LP now offers 150mW of CW output at 488nm, while the Sapphire 561 LP provides 200mW of power at 561nm.
These two lasers, available in an OEM and CDRH configuration, measure 125mm x 70mm x 34mm, making them easy to integrate into benchtop instrumentation.
Integration is further aided by the high efficiency of the optically pumped semiconductor laser (OPSL) technology utilised in Sapphire LP series products, which produces minimal waste heat.
A USB port interface (OEM version only; in addition to the analogue and RS-232 ports previously available) enables simple software control of laser operation and readout of all laser operating and status parameters.
A new OEM controller board, available for all Sapphire LP products, is approximately half the size of the previous version.
The Sapphire LP 488 and Sapphire LP 561 are primarily targeted at life science applications, such as flow cytometry, confocal microscopy and sequencing in genomics and proteomics.
In these uses, their combination of small size and high output power enable construction of highly compact instrumentation.
These lasers also deliver excellent beam quality (M is less than 1.1), low noise (less than 0.25 per cent rms from 20Hz to 2MHz) and high pointing stability (less than 30 urad), resulting in stable, low noise instrument operation.
