The OL 750-10T/R Mirror Collimating Optics Module serves as a convenient, easy to use attachment for the OL Series 750 System when measuring spectral transmittance or specular reflectance at a fixed angle. It consists of a pair of front surface aluminized mirrors mounted in a rugged fixture which is attached to the exit port of the OL Series 750 Monochromator. The high degree of uniformity of the collimated, monochromatic beam enables the user to make accurate measurements of spectral transmittance and specular reflectance.

The OL 750-10C Mirror Collimating Optics Module consists of a pair of front aluminized mirrors mounted in a rugged fixture which is attached to the exit port of the OL Series 750 Monochromator.The high degree of collimation and superb uniformity produced by the OL 750-10C/OL Series Monochromator combination enables it to be used as an excellent source of collimated monochromatic flux, with a beam diameter of up to 2 inches, as well as a superior source for performing Detector Spectral Response measurements on relatively large area detectors.

The OL 740-70 is used with OL Series 750 Automated Spectroradiometric Measurement System for measuring the diffuse or total hemispherical reflectance of materials. Accurate reflectance measurements can be made with the specular component included or excluded. Specular (mirror) samples can also be measured at 10° incident angle. Spectral transmittance of clear and diffusely transmitting materials can also be measured. The attachment uses a true double beam optical design with a manual beam switch which minimizes errors found in less accurate single beam designs. The OL 740-70 can be used over the 250 to 2500 nm wavelength range.

The OL 740-70G is a gold coated version of the OL 740-70 described above. It is used over the wavelength range of 2 to 18 µm.

OL 750-75MA Specular Reflectance Attachment

The OL 750-75MA is used with the OL Series 750 Automated Spectroradiometric Measurement System in conjunction with OL Series 740-20 Source Attachment for measuring the spectral specular reflectance of materials as a function of both wavelength and angle of incidence. The all-mirror optical design enables the attachment to be used over the entire 0.2 to 30 µm wavelength range. Accurate measurements can be made without the use of a standard (calibrated mirror) by directly measuring the incident beam. The flexible receiver design allows the angle of incidence to be selected from 10° to 60° with an accuracy of ±0.1° .

The OL 740-4P Off-Axis Parabolic Telescope is designed to facilitate a broad range of radiometric measurements over the entire UV to IR wavelength range. The telescope can be interfaced to the entrance port of the OL Series 750 Monochromator system to measure spectral irradiance or radiance of collimated, point or diffusely radiating sources, or it can be interfaced to the exit port to obtain a highly collimated, monochromatic flux level and used to calibrate various detectors or radiometer systems. The telescope may also be interfaced to the OL 480 Blackbody Source to obtain a collimated, broadband source at various blackbody temperatures, or to the OL 300 Low Light Calibration Source (with starlight shaping filter) to obtain a collimated star standard.
