OL 740-20A-3RP Set of (3) Replacement Lamps for OL 740-20A Source Attachment

The OL 740-20A-3RP is a set of (3) Replacement Lamps for the OL 740-20A Source Attachment. The OL 740-20A is furnished with a 150-watt quartz-halogen lamp for use in the 0.25 – 3.5 μm spectral region. The recommended lamp power supply is the OL 410-200 Precision Lamp Source.

The OL Series 740-20 High Intensity Source Attachments are designed specifically for use with the OL Series 750 Automated Spectroradiometric Measurement System. With the appropriate constant current power supply, these source attachments provide the intense, highly stable source of radiant intensity that is required for accurate measurements of detector spectral response, spectral reflectance, and spectral transmittance. The attachments consist of a source housing with all-mirror imaging optics matching the f/4 optics of the monochromator, which easily mounts to the monochromator entrance port via a spin ring. The OL Series 740-20 is available in (4) versions for use within a portion or the entire 0.2 to 30 μm wavelength region.
