BFi Optilas has collaborated with Photoresearch to launch the next generation of Spectrascan spectroradiometers. The PR-730/735 offers twice as many detectors as the PR-705/715, the industry standard, and it offers higher resolution while being more sensitive and producing no polarization error or stray light. It comes with USB, Bluetooth wireless and RS-232 interfaces and a high-resolution colour touch-screen display. The PR-730 version has a 380- to 780-nm spectral range, while the PR-735 has a 380- to 1100-nm range. Applications include lamp standards metrology, phosphor research, tooth analysis and military displays.
