New range of IR and Red Laser Diodes from QSI

ProPhotonix extends its range of red laser diodes and IR laser diodes, with the addition of the new QL63F7S – A/B/C, QL65D7S- A/B/C- PS and QL78F8S – A/B/C laser diodes from QSI. With these new products, ProPhotonix is offering new laser diodes ideal for eye-safe sensors, cameras, and optical module applications.

This blog post provides an overview of the new Red and IR laser diodes and their applications.

Red Laser Diodes

QL63F7S – A/B/C 635nm laser diode is ideally suited for integration into sensor and laser module applications. Its rated optical power output is 10mW CW and it is offered in a compact 5.6mm package.

For similar applications at 650nm, the new QL65D7S – A/B/C – PS laser diode has a rated output power of 5mW and a low operating current. Additionally, the low power level makes the QL65D7S – A/B/C – PS laser diode ideally suited to applications such as cameras, sensors, and laser modules. This red laser diode operates with a maximum drive current of 33mA.

IR Laser Diode

The IR laser diode, QL78F8S – A/B/C is ideally suited to industrial optical module and sensor applications. This 780nm device has an output power 10mW, with a built-in photodiode for monitoring laser diode performance. It is available with three different pin configurations within a package of 5.6mm. This laser diode can be operated at a maximum temperature of 80°C.
