OL Series 426 Low-Light-Level Integrating Sphere Calibration Standard
The OL Series 426 is a low light level calibration standard designed for accurately calibrating very sensitive microphotometers, image intensifiers, telephotometers, and imaging spectroradiometers for photometric, radiometric, or spectroradiometric response at moderate to extremely low light levels. It serves as a highly accurate, large area, uniform, diffusely radiating source with a near normal luminance that can be varied over 6 decades with essentially constant colour temperature. A separate electronic display console/power supply is included.

OL Series 455 High-Intensity Integrating Sphere Calibration Standard
The OL Series 455 is a high-intensity, uniform, diffusely radiating calibration standard. It is used for accurately calibrating imaging spectroradiometers, radiometers and photometers. The OL455 consists of a source module/optics head and a separte electronic display console/power supply. Source modules are avalable with integrating spheres having diameters of 101mm (4"), 152mm (6"), 203mm (8"), 305mm (12") or 457mm (18") with corresponding exit and radiating ports of 25mm (1"), 38mm (1.5"), 51mm (2"), 76mm (3") or 152mm (6"). The OL455 can also be operated with calibrations of spectral radiance over the 300nm to 2500nm wavelength region.

OL455-6KSA Ultra High Uniformity Calibation Standard

The new OL 455-6KSA incorporates three new extremely innovative design features:

  • It has a unique elongated sphere design. This elongation of the sphere reduces the non-uniformity by a remarkable factor of 10x
  • The unit comes with a new aperture drive design, which increases the accuracy while dramatically shortening the seek time for finding a specific luminance target
  • It also has a heated monitor detector which holds the detector at a steady temperature to reduce settling time and non-linearity as you increase or decrease luminance.

OL458-4 White LED-based Calibration Standard

The OL 458-4 is a NIST-traceable white LED-based integrating sphere calibration standard, designed for accurately calibrating micro- and telephotometers, image intensifiers and imaging photometers. A proprietary design allows for true continuous spectrum across the visible range. Precision source temperature control delivers extremely stable output over long periods of usage. The design and output are customisable upon request.

OL Series 462 Automated High-Intensity Integrating Sphere Calibration Standard
The OL462 is an automated, high-intensity integrating sphere calibration standard designed for accurately calibrating very sensitive instrumentation. The OL462 consists of an optics head and a separate controller. The unattended calibration feature of the OL462 enables the user to vary any of these parameters as a function of time. A calibration for spectral radiance over all or part of the 300nm to 2500nm region is also available.

OL Series 466 Automated Low-Light-Level Integrating Sphere Calibration Standard
The OL Series 466 Automated Low-Light-Level Intergrating Sphere Calibration Standard is designed for accurately calibrating very sensitive instruments such as microphotometres, telephotometers, image intensifiers and imaging spectroradiometers for photometric, radiometric or spectroradimetric response at moderate to extremely low light levels. It serves as a highly accurate, large area, uniform, diffusely radiating source with a near normal luminance that can be varied over decades with essentially constant colour temperature. It includes a computer interface (RS232 as standard, IEEE-488 optional) for use in automated test stations.

OL Series 480 Variable Temperature Blackbody Calibration Standard
The OL480 serves as an accurate, variable temperature (100°C to 1200°C) blackbody calibration standrd. It is extremely useful for calibating infrared radiometric and spectroradiometric measurement systems. The OL480 has an emmisivity of 0.99 +/-0.01 and an uncertainity in the digital temperature readout of +/-2°C.
