    2.High Quality Ruled Gratings Sample Efficiency Curve – 120/12µ Ruled Diffraction Grating. These replicated diffraction gratings are produced from high-quality ruled master gratings and are intended for use in spectrometers and monochromators where cost and high efficiency are of primary concern. Ruled diffraction gratings have a higher peak efficiency than holographic diffraction gratings

    3.Transmission Transmission gratings allow for simple linear (source -> grating -> detector) optical designs that can bebeneficial in making compact fixed grating applications such as spectrographs. In addition, the performance of transmission gratings is insensitive to some types of grating alignment errors. Transmission and reflection

    4.A plane grating is designed to meet the specifications for size, wavelength range, angle of incidence and angle of diffraction, but not for a specific focal length for the optical system. Therefore it is possible to use the same grating for different optical arrangements as long as the four previously mentioned parameters are the same.

    5.Grating Type: Unequally spaced curved-groove laminar-type replica grating *1: Blank material: BK-7 or equivalent: Dimension tolerance ±0.2(W)×±0.2(H) Center thickness tolerance ±0.5(T) Grooved area: Total area less 2mm strip around the perimeter: Effective area: Total area less 5mm strip around the perimeter: Groove density tolerance ±0.5%

    Transmission Gratings with AR Coating, UV, VIS, NIR

    1.UV, VIS and IR Transmission Diffraction Gratings. A transmission grating offers a basic simplicity for optical designs that can be beneficial in fixed grating applications such as spectrographs (aka optical spectrometer). The incident light is dispersed on the opposite side of the grating at a fixed angle.

    2.High Quality Ruled Gratings Sample Efficiency Curve – 120/12µ Ruled Diffraction Grating. These replicated diffraction gratings are produced from high-quality ruled master gratings and are intended for use in spectrometers and monochromators where cost and high efficiency are of primary concern. Ruled diffraction gratings have a higher peak efficiency than holographic diffraction gratings

    3.A grating with high efficiency is more useful than one with lower efficiency in measuring weak transition lines in optical spectra. A grating with high efficiency may allow the reflectivity and transmissivity specifications for the other components in the spectrometer to be relaxed. Moreover, higher diffracted energy may imply lower

    4.could benefit from a ruled grating blazed at that wavelength. Wavelength Range:The spectral range covered by a grating is dependent on groove spacing and is the same for ruled and holographic gratings having the same grating constant. As a rule of thumb, the first order efficiency of a grating decreases by 50% at 0.66 λ B and 1.5 B

    5.Spectral filters (optical fiber filters) Dispersion compensators in telecommunications. FBG spectral specifications are based on the periodic change of fiber core refractive index at different lengths and depend on the optical heterogeneity diffraction. A fiber Bragg grating can be of different lengths from 0.3 to 50 mm.

    4.Fiber Grating. Fiber gratings formed at low intensities are generally referred to as Type I. Another type of grating is a damage grating formed when the energy of the writing beam is increased above approximately 30mJ [119]. From: Fiber Bragg Gratings (Second Edition), 2010. Related terms: Amplifier; Optical Fibers; Bragg Cell; Wavelength

    5.Diffraction Gratings are optical components used to separate light into its component wavelengths. Diffraction Gratings are used in spectroscopy, or for integration into spectrophotometers or monochromators. Diffraction Gratings consist of a series of closely packed grooves that have been engraved or etched into the Grating’s surface.
