Expected spectral resolution and simultaneous bandpass are also influenced by how light is coupled into the spectrograph, the central wavelength of interest and associated grating “working angle”, as well as the detector pixel array format at the output plane. Some of these trade-offs can be assessed with the Andor resolution calculator for Kymera and Shamrock Czerny-Turner spectrographs.

Ordered 4 camera mounts for broadcast Sunday mass in our church during pandemic. Mounts very strong, easy to install (dream access to the mounting holes. Looks very professional.

This product is amazing. I’m using it to hold a sony A6600 with tamron 28-75 f2.8 for church streaming. It’s doing an amazing job so far. I’m planning on buying more.

I ordered three of the mounts but didn't open the boxes at first. When I did i realized the mounts had been shipped without the Ball Heads. I called and within minutes the problem was found and heads were on their way to me. GREAT customer service. Already had one in use and am looking forward to implementing these soon.

The dispersion and efficiency of a grating are dependant on the distance between adjacent grooves and the groove angle. Gratings are generally better than prisms - they are more efficient, they provide a linear dispersion of wavelengths and do not suffer from the absorption effects that prisms have which limits their useful wavelength range.

The dispersed light is then re-imaged by the spectrograph and the required wavelength range is directed to a detection system. Gratings consist of equally spaced parallel grooves, formed on a reflective coating and deposited on a substrate. The shape of the grooves (blaze angle) influences what wavelength range the grating is best optimised for.

A diffraction grating is an optical element, which separates (disperses) polychromatic light into its constituent wavelengths (colors). The polychromatic light incident on the grating is dispersed so that each wavelength is reflected from the grating at a slightly different angle. The dispersion arises from the wavefront division and interference of the incident radiation from the periodic structure of the grating.

where: n is the order of diffraction, λ is the diffracted wavelength d is the grating constant (the distance between successive grooves) θi is the angle of incidence measured from the normal and θd is the angle of diffraction measured from the normal. The diagram above shows the orders of the diffracted wavelength. As well as positive orders, light can also be diffracted in the opposite direction (i.e. n = -1, -2 etc.) Higher orders may also appear, but these decrease in intensity. Usually the first order lines (n=1 or n=-1) are the most intense.

This sturdy all metal wall camera mount is designed to be installed on a flush wall with 4 screws (at least 2 in stud) or other captive wall fasteners. The end includes a mini ball head for attachment to the camera, which allows for camera angle adjustment. The ball head camera mount is easily removable with a thumb screw for camera servicing. The maximum camera weight is 6 pounds, and attachment of the plate to the wall must be very strong. The solid 5/8 inch baby pin arm is 8 inches long.  The wall plate is 3.2". x  6.0". The ball head has a 1/4" x 20 screw thread and mounts most cameras.

These influence the choice of grating line density, blaze angle/wavelength, master (different masters for a given line density and blaze angle yield different efficiency and polarisation characteristics) and grating size.
