OL Series 756 Portable UV-VIS Spectroradiometer

The OL 756 High-accuracy UV-VIS Spectral Measurement System is our newest state-of-the-art compact, double monochromator system for spectral measurements over the 200 – 800 nm wavelength range.

With a maximum speed of 200 nm per second (Quickscan Mode), the OL 756 is the fastest scanning portable spectroradiometer available.

This versatile portable system combines the electronics and optics in a single package and features: a USB interface, high sensitivity, extremely low stray light levels, narrow bandwidths, large dynamic range, and high wavelength accuracy and precision. The OL 756 is ideal for performing solar spectral measurements over the full range in about 3 seconds. It also operates on 12V DC power, providing portability for remote measurements.

Fast and accurate spectroradiometric measurements can be performed in the laboratory or outside with the battery/DC power option for total portability under demanding field conditions. The detector consists of a high sensitivity, temperature-stabilized, S-20 response photomultiplier. The double monochromator utilizes concave, holographic gratings with peak efficiencies at 300 nm. The five sizes of fixed slits that are provided enable the user to vary the half-bandwidth from 0.8 to 5 nm.

The applications software includes calibration and measurement routines for performing measurements of:

Source Spectral Analysis

Radiance

Irradiance

Spectral Reflectance

Spectral Transmission

Other software features include:

Color CIE diagrams with zoom capability for precise color studies and sequential measurement result accumulation on the diagram

An impressive suite of calculations are performed automatically, including chromaticity, CCT, CRI, photobiological parameters, etc.

Highly flexible plot manipulation shows up to 10 scans on a single graph. Select and/or protect one or many with “hide scan” or “lock scan” features.

Favorite calibration file list saves searching and selection time by showing recently used files.

A supervisor password protects data and prevents measurement setups from being altered by unauthorized personnel.

Results can be sent directly into Excel for custom analysis and into Word templates for custom report generation

Savitzky-Golay plot smoothing reduces noise while preserving features such as peak height and width.

Optional ActiveX controls available for custom programming.

A variety of input optics are also available, such as the OL IS-670 6” PTFE coated integrating sphere with near-ideal cosine response for spectral irradiance measurements of the most demanding light sources and matching optical fused silica dome window for use in harsh environments without affecting the cosine response.

OL 756 Optional Accessories include:

OL 756-150 Dual Calibration Check Source Module

OL 756-CC Carrying Cases

OL 756-BAT Battery Power Pack

Cosine corrected integrating spheres (submersible sphere for underwater measurements up to 20m)

Telescopes and microscopes for spectral radiance measurements

Quartz fiber optic probe coupling

NIST-traceable calibration standards
