LED radiometer SpectraScan® PR-740

The SpectraScan® Spectroradiometer PR-740 is JADAK’s enhanced 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-740 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. Operating at 20 times more sensitivity than the PR-730 and 250 times faster, the PR-740 is configured with 512 detector elements and has a wide dynamic range of 5.00E–6 – 5.00E1 (without external neutral density filters), spectral resolution of 0.781 nm per pixel, and spectral range of 380–780 nm, accompanied by an automated measure shutter (data is reported every 1 nm). 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) ).
