The NIR MicroHR is a 140 mm focal length spectrometer featuring gold optics (for increased through-put in the NIR spectral region) and interchangeable gold gratings for optimization of optical components and wavelength range selection. A completely manual spectrometer, the NIR MicroHR offers full flexibility of wavelength selection with no electronic thermal emissions. A high-precision wavelength counter allows for extremely accurate and repeatable wavelength positioning. Other features include fixed of micrometer slits and a mechanical shutter for true dark subtraction. In combination with a Symphony STE of LN2 InGaAs Array, the NIR MicroHR is the perfect instrument for NIR spectroscopy, laser characterization, NIR fluorescence, absorption and NIR filter characterization.
