The SpectraScan® Spectroradiometer PR-788 Extended Dynamic Range is JADAK’s ultra-sensitivity portable solution for spectral based photometric and colorimetric light measurements, designed for applications requiring precise light measurements from a range of light sources, such as display monitors and projectors, reflective surfaces, and industrial applications (visual display testing, LED testing, film and video post-production, auto/aerospace displays, and dental color testing).
A handheld, completely portable battery powered (Li-ion, USB charger) unit for stand alone operations, the PR-788 interfaces with USB, and optional Bluetooth® or RS-232, with a Secure Digital (SD) port to allow users to store measurement data on removable media. Designed to measure from the black to full white without external attenuation or optical geometry changes, the PR-788 is configured with 512 detector elements and has an extended dynamic range of 3.42E -5 to 1.71E4 (without external neutral density filters), and spectral resolution of 1 nm per pixel. Approximate measurement time is 300 ms. Available with 8 Measuring Apertures (2°, 1°, 1/2°, 1/4°, 1/8°, 0.2°, 0.1°, 0.1° x 1° (Hor . Slit), 0.1° x 2° (Ver. Slit), 0.5° x 1.5° (Hor. Slit) ).
