Roof Prism, Amici Roof Prism, Schmidt Prism, Roof Pentaprism Overview: A roof prism, also called a Dachkanten prism or Dach prism is a reflective prism containing a section where two faces meet at a 90° angle, resembling the roof of a building and thus the name. Reflection from the two 90° faces returns an image that is flipped laterally across the axis where the faces meet. Characteristic for a roof prism is that the beam is split in half, with one half of the beam hitting first one face then the other face, while it is invert for the other half of the beam. Therefore, a roof prism can be used only with some distance to focal planes, or the "edge" of the roof would introduce slight distortions. Furthermore, the angle between the two faces has to be very close to 90°, or image quality would be degraded.
The simplest roof prism is the Amici roof prism(Roof Right Angle Prism), with other common roof prism designs being the Schmidt prism and probably the best known being the roof pentaprism.
Manufacturing Capacity of Roof Prism:
An Amici roof prism, sometimes called an Amici prism or right angle roof prism, is a type of reflecting prism used to deviate a beam of light by 90° while simultaneously inverting the image. It is commonly used in the eyepieces of telescopes as an image erecting system and any optical instrument where it is desirable to take an inverted image from an objective, turn it right side up, and bend it through a 90° angle in order to maintain the correct visual orientation.
Roof pentaprism is a variant of Penta Prism which is commonly used in the viewfinder of single-lens reflex cameras.

UV FS Spherical Glass Lens MgF2 Coating Double Convex Lens With Fixed Mount
Double Convex (Bi-Convex) Spherical Lens, UV Fused Silica, Finite Imaging Lens Overview: Double-Convex (DCX) Lens, also referred to as bi-convex lens, has two positive, symmetrical faces with equal radii on both sides. These lenses are generally recommended for finite imaging applications. Bi-convex lenses are most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object distances (conjugate ratio) is between 0.2 and 5. Star -
CaF2 Cylindrical Concave Lens Curved Surface Cylinder Laser Lenses
Plano Concave Cylindrical Lens, Rectangular, UV Fused Silica Overview: Plano Concave Cylindrical lens is also called negative cylindrical lens act as plano-concave spherical lenses, except on only one axis. These lenses are used in applications that require one dimensional shaping of a light source. A typical application is to use a single cylindrical lens to turn a collimated laser into a line generator. Pairs of cylindrical lenses may be used to anamorphically shape images. -

Large Feild Angle Optical Waveplate 12.7mm True Zero Order Waveplate
True Zero Order Λ/2 Half Wave Plate, Large Feild Angle, For Imaging Systems Overview: Comparing with normal two plates design Zero order waveplates having a relatively larger thickness which reduces the field angle, the True zero order wave plates are made of a very thin plate or cemented with a BK7 substrate, which ensures the best possible field angle, temperature and wavelength performance. True zero order waveplate is widely used in laser Lab and optical instrument. True
