Laser diodes are first at 705nm

Available in the UK from Photonic Products, the Opnext HL7001MG and HL7002MG are innovative laser diodes from Opnext with a pioneering a lasing wavelength of 705nm.

The Opnext HL7001MG and HL7002MG are designed for use in biomedical applications such as blood analysis and endoscopy which benefit from these infra-red laser diodes' high reliability, low operating current requirement and high output power.

The lasing wavelength of 705nm at 50mW offers high permeability for living tissue and low absorption of haemoglobin and water.

The Opnext HL7001MG and HL7002MG laser diodes have optical output power of 50mW CW (typical) 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 -10 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.

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 whilst improving the quality.

"We are proud to add this cutting-edge laser diode to our range of Opnext laser diodes", said Damon Cookman, Managing Director, Photonic Products.

"Opnext continues to innovate and produce high quality laser diodes, and Photonic Products is delighted to be an authorised distributor".

Opnext laser diodes are lead (Pb) free in compliance with the RoHS Directive.

All Opnext laser diodes are registered with the FDA of the USA, and each laser diode is classified into class II, IIIa, or IIIb, according to the combination of the optical output power and wavelength values.
