StellarNet, Inc. has announced its BLACK-Comet series of Concave Grating Spectrometers. The use of an aberration corrected, holographic concave grating uses no mirrors to minimize stray light, while projecting a flat field on the detector and providing uniform resolution over the entire range. Additionally, the grating has a dual blaze to giving high efficiency in both the UV and NIR wavelengths with 4 wide ranges available. The units are vibration tolerant, durable over long periods of time, and suitable for just about any lab and/or field measurement
