Transmission-type holographic diffraction grating spectrometer

Transmission Holographic Diffraction Grating Spectrometer; The non-scanning high-performance spectrometer produced by P&P Optical Design is currently the only spectral detection system on the market that uses volume phase holographic (VPH) diffraction grating technology with a transmission design. This system features low optical aberration and strong light collection capability, making it very suitable for spectral testing of weak light signals. P&P Optical's high-performance spectrometer can achieve high spectral resolution and high dynamic range spectral testing over the 320nm -2500nm range.; P&P Spectrometer's Unique Features: ; The transmission gel grating spatially isolates the collimating part and the focusing part of the system, while the refractive optical system eliminates many of the aberrations and stray light common in other spectrometer designs. This enables our spectrometer to measure the entire spectrum at the same time without moving parts. By carefully matching the spectral range to the detector capacity, P&P Optica spectrometers outperform many competitors in the UV/VIS/NIR spectral range.; This system has minimal aberration and the highest light throughput, making it best suited for low-light-level spectroscopy. Over the spectral range from 250 to 2500nm, P&P Optica spectrometers can provide high dynamic range and high spectral resolution.; VPH Spectrometer Technical Parameters; Parameter; Value; Size; 32cm L x 12cm W x 10 cm H; Weight; typically <4 kg; F/number; F/3; Spectral range (free of second order effects); 90-95% of an octave in the 350 nm to 2500 nm range; Spot diameter; 19 µm @ 1000 nm in 25.4 x 9 mm^2 area; Spectral resolution (0.024 mm wide pixels); 0.5 nm @ 400 nm and 2 nm @ 2000 nm; Linear dispersion; 90%-95% of an octave per inch; Maximum detector size; 25.4 x 12.7 mm; Dynamic range of a single 0.024 by 0.024 mm^2 pixel; > 3, 000; Dynamic range, binning along 2 mm slit; > 55, 000 (detector dependent); Dynamic range, binning along 8 mm slit; > 300, 000 (up to 1, 000, 000 with averaging over a number of measurements)
