Abstract
A linear axis spectral analysis system is enclosed. The spectral analysis system utilizes a prism-volume holographic transmission grating-prism combination to achieve a linear axis between input and detector. This design, when held with low thermal expansion materials, is extremely insensitive to temperature and vibration, allowing for enhanced accuracy without the need of temperature control. Further, the spectral analysis system provides the ability for extreme compactness.
Claims32
A device used to separate wavelengths of light in which all optical elements are configured on a linear axis, said device comprising:
- An entrance slit through which photons pass;
- A collimating lens to receive and collimate the photons that passes through the slit;
- A first prism used to receive photons from the collimating lens;
- A holographic optical element to receive photons from the first prism and diffract the photons;
- A second prism to receive the diffracted photons from the holographic optical element;
- A focusing lens to receive the diffracted photons from the second prism and direct the diffracted photons on to a detector.
A device used to separate wavelengths of light that uses a prism-grating-prism series combination.
