Compact laser modules suit handheld devices

Photonic Products has a new range of compact 8mm-diameter laser diode modules for customers requiring a small laser module to be integrated into systems and handheld instrumentation where space is at a premium.

Typical applications are targeting, industrial alignment such as pre-press plate alignment and laser alignment for label and wrapper cutting machinery, and medical applications such as patient positioning.

The laser modules measure just 25.5mm in length, with a diameter of only 8mm and are extremely efficient and reliable.

The 650nm laser diode modules produce an elliptical, collimated output beam of 3.5 x 1.5mm, with output powers of 0.9 or 4.5mW.

Operating voltage is from 3 to 6V DC at a typical operating current of 30mA (0.9mW) or 40mA (4.5mW).

Beam divergence is less than 1mrad and operating temperature range is -10 to +50C.

The 635nm laser diode modules produce an elliptical, collimated output beam of 3.5 x 1.5mm, with output powers of 0.9 or 4.0mW.

Operating voltage is from 3 to 6V DC at a typical operating current of 30mA (0.9mW) or 40mA (4.5mW).

Beam divergence is less than 1mrad and operating temperature range is -10 to +40C.

The laser modules consist of a brass housing, laser diode, drive circuit and adjustable collimating or focusing lens.

The lens may be adjusted to produce either a collimated beam or focused spot.

Electrical connections are made via external flying leads.

They have been designed as a complete laser diode solution for OEM companies.

For applications requiring electrical isolation of the laser module housing, a hard anodised aluminium housing version of this compact laser module is available.
