1550nm 10mW Clarity PFR Precision Frequency Laser Module
The Clarity PFR continues to provide wavelength references for primary frequency laser sources. This module is targeted at applications where small size is important, or where the product will be embedded as an OEM component into a customer's product. The laser has an absolute frequency accuracy of ±0.1 pm and can be ordered at several wavelengths from 1300 nm to 1610 nm. Please consult the factory for availability. The laser can be supplied in a rugged aluminium housing or even at board level for easy integration into customer products. Custom firmware to meet specific customer requirements is also available.
