Title: Aberration-free Imaging Spectrograph
BACKGROUND
The National Institute for Standards and Technology’s (NIST) Sensor Science Division (SSD) is involved in the development of a new measurement and calibration capability using a single photon spectroradiometer for calibration of extremely dim light sources such as nano-LEDs, LEDs used for calibration of photon-multiplier tubes, and sphere sources used for calibration of night vision goggles. The single photon spectroradiometer is composed of an aberration-free imaging spectrograph to achieve the highest imaging quality and a single photon digital camera to measure single photon sources. This acquisition is for the aberration-free imaging spectrograph.
The system shall meet or exceed the minimum requirements identified below. All items must be new. Used or remanufactured equipment will not be considered for award. Experimental, prototype, or custom items will not be considered. The use of “gray market” components not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.
The contractor shall provide one (1) aberration-free imaging spectrograph that is compatible with Hamamatsu’s single-photon digital camera Model Orca-Quest 2 in accordance with the technical specifications listed below:
- Contract Line Item 0001: Aberration-free imaging spectrograph
Quantity: One (1)
The Contractor shall provide an aberration-free imaging spectrograph that meets the following minimum specifications:
- 100 % compatible with Hamamatsu’s Orca-Quest 2 digital cameras for system integration.
- LabVIEW software for control and data acquisition.
- Aberration-free 320 mm focal length Schmidt-Czerny-Turner imaging spectrograph with advanced optics and superior MTF and spectral resolution.
- Interchangeable motorized triple grating turret with torque-limiting kinematic mount.
- f/4.6 aperture ratio.
- Linewidth (FWHM) of 1.5 pixels or better with a 20 micron pixel pitch.
- Spectral resolution of 0.065 nm or better at 546 nm with a 1200 groove/mm grating.
- Spatial resolution ≥25 line pairs/mm @ 50% modulation, measured at focal plane center
- Spatial resolution ≥10 line pairs/mm @ 50% modulation, measured over 27 x 8 mm focal plane
- Zero astigmatism at any wavelength with any grating at all points in the focal plane.
- Zero coma at 500 nm with 1200 gr/mm grating.
- Wavelength accuracy of 0.2nm.
- Wavelength Repeatability of +/- 0.015 nm.
- Internal angle of 17.7°.
- Mirror focusing with internal micrometer adjustment.
- On-axis grating rotation design.
- Planar 68 x 68 mm gratings are on extra-thick substrates for improved flatness.
- Motorized or kinematic slit(s) with optional slit shutter.
- Shutter control port from camera at rear of instrument.
- Can resolve >200 distinct spectral channels on 2D arrays on CCD and CMOS cameras up to a height of 22 mm.
