Laser-diode collimators accurately align beams

These comprise a micro laser-diode collimator that measures just 4.5mm in diameter and two miniature laser-diode collimators that measure just 6mm in diameter.

The 300-0444-00 micro laser-diode collimator offers high bore-sighting accuracy of <0.2 and the two miniature laser-diode collimators offer bore-sight error of 0.4 in the standard version or 0.05 boresight accuracy in the high-precision version.

The 300-0444-00 micro laser-diode collimator has a diameter of 4.5mm and 8mm length.

It has been designed for use in applications requiring high beam-alignment accuracy where size is a critical factor.

It also has a high-quality glass lens that offers improved optical performance over the operating temperature range.

It has a lasing wavelength of 650nm, elliptical output beam of 8.0 x 6.5mm at five metres, high bore-sighting accuracy of <0.2, beam divergence of 0.5mrad max, collimated output power of 3mW, and pointing stability of <0.2mrad/C.

Operating current is 25mA and operating temperature range is from -10C to +70C.

It consists of a brass housing, 3.3mm diameter laser diode and glass collimating lens in a lightweight 4.5mm cylindrical package.

The two miniature laser-diode collimators in the range are intended for use in applications requiring high beam-alignment accuracy.

They measure just 9.1mm in length and 6mm in diameter.

They have a lasing wavelength of 650nm, elliptical output beam of 2.7 x 6mm at five metres, beam divergence of 0.5mrad max, collimated output power of 5mW max, pointing stability of <0.2mrad/C and high bore-sighting accuracy.

Operating current is 30mA, threshold current is 20mA and operating temperature range is from -10C to +70C.

They consist of a brass housing, 5.6mm-diameter laser-diode and collimating lens in a lightweight 6mm cylindrical package.

These tiny laser-diode collimators have been designed as complete low cost, high-volume systems for OEM use.
