Photonic Products has been named the authorised distributor of the 705nm semiconductor laser diode from Opnext.
The Opnext HL7001MG/HL7002MG laser diode is designed for use in biomedical applications such as blood analysis and endoscopy.
The lasing wavelength of 705nm at 50mW offers high permeability for living tissue and low absorption of haemoglobin and water.
The diode features: optical output power of 50mW CW (typ) at a lasing wavelength of 705nm; low operating current of 75mA; low operating voltage of 2.5V; LD reverse voltage of 2V; PD reverse voltage of 30V; a low threshold current of 30mA; and monitoring output current of 0.15mA.
The operating temperature range is -10C to +60C.
Supplied in a 5.6mm package with 3P-type common cathode pin configuration (HL7001MG) or 1N pin configuration (HL7002MG), this is a single longitudinal mode Opnext laser diode with a built-in monitor photodiode.
Photonic Products said the 5.6mm package size is ideal for small, energy efficient medical sensor equipment and low-power optical measurement applications, and enables a reduction in the size of current biomedical measurement equipment while improving the quality.
Opnext laser diodes are lead (pb) free in compliance with the RoHS Directive.
All Opnext laser diodes are registered with the US' FDA and each laser diode is classified into class II, IIIa, or IIIb, according to the combination of the optical output power and wavelength values.
