MicroHR
NIR - A
Compact, Versatile Czerny-Turner NIR Spectrometer
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.
