The high resolution and efficiency of Echelle gratings come at the cost of a more complex optical setup. Multiple diffraction orders often overlap in the spectrum produced by an Echelle grating, which requires the use of additional optics, such as prisms or cross-dispersive gratings, to spatially separate the orders for analysis.

Precision electroformed parabolic reflectors, also known as paraboloid or paraboloidal mirrors, are designed for various illumination and light collection applications where a collimated, concentrated beam of light is desired. Their broad 200 nm to 10 µm spectral range makes them ideal for applications where lenses are either limited by their transmissive properties or are too costly to manufacture.

Echelle gratings utilize a phenomenon known as diffraction, which occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. The Echelle grating is tilted at a steep angle, known as the blaze angle, to direct most of the diffracted light into a preferred order, often much higher than those used in typical diffraction gratings. This blaze angle enhances the efficiency of the grating in that order, resulting in brighter and clearer spectra.

Echelle gratings are primarily used in spectroscopy for the analysis of atomic and molecular spectra. Specifically, they serve in the following roles:

Optiforms uses an advanced manufacturing process called Electroforming to produce precision optical components. Electroforming allows Optiforms to consistently replicate complex forms using a single master tool, reducing cost per part and ensuring a high degree of control, precision and reliability.

An Echelle grating is a type of diffraction grating characterized by its constructively large step height and blaze angle, designed for high-resolution spectroscopic applications. Echelle gratings are used to disperse light into its component wavelengths. However, unlike conventional gratings, they are optimized to work at high diffraction orders, which allows for the separation of spectral lines that are extremely close in wavelength.
