Reflectors - Elliptical and Parabolic

 MC-233 Elliptical and MC-234 Parabolic Reflectors

25mm x 25mm (1" x 1") parabolic and elliptical reflectors are available suitable for use with Series 12 and Series 21 range of IR sources.

The reflectors are made from machined and polished aluminium (they are not anodised). A grub screw is used to fix the IR source into position.

The IR-12, IR-12K and IR-21 are mounted into the reflectors from the base side. The IR-21V is mounted into the reflectors from the reflector side.

Please note that the reflectors get very hot whilst in normal operation.

The angular output for a IR-12K with a MC-234 has been tested with a 75mm spacing between the emitter and the detector. The resulting curve is shown below. The full width at half maximum (FWHM) is approximately 30 degrees.
