1. Prism definition
A prism (Prism) is an optical element that deflects light according to a specific angle between the emitted light and the incident light. In the optical path, the prism has the function of changing the angle between the emitted light and the incident light (such as deflection 90°, 180°, etc.), shifting the light, and changing the image direction. Prisms are widely used in laser research, laser optical systems, optical imaging, machine vision, life sciences, biomedicine, and other fields or products. Huasen Optical and Electronics can provide a variety of prism stock standard products, such as K9 standard precision right-angle prism, K9 high precision right-angle prism, UV fused silica standard precision right-angle prism, UV fused silica high precision right-angle prism, K9 pentagonal prism, K9 Dove prism, K9 roof prism, K9 corner reflector (K9 corner prism), ultraviolet fused silica corner reflector (ultraviolet fused silica corner prism), wedge prism, etc. While we provide a variety of standard prism products, we can also provide you with customized prism services according to your actual needs, such as the change of prism size, the improvement of parameter indicators, and the change of coating requirements.
2.Types of prisms
2.1 K9 standard precision right angle prism
Right-angle prisms are generally used to bend the image path or turn the light path by 90°. Combining two right-angle prisms can also synthesize images and shift beams. For applications with larger incident angles, inclined aluminum film prisms are recommended. Huasen Optical and Electronic offers right-angle prisms in a variety of sizes, and coating options include aluminum and antireflection coatings.
2.2 K9 pentaprism
The pentaprism can deflect the light by 90°. It is a five-sided prism. A slight movement of the prism will not cause too much influence on the reflected light, so it can be used to define a right angle.Huasen Optical and Electronics provides five-sided prisms of various sizes, and coating options include aluminum coating and anti-reflection coating.
2.3 K9 Dove Prism
Dove prism is a kind of image rotator. After the light passes through this prism, the image is reversed by 180°. In addition, when the prism is rotated about its optical axis, the rotation angle of the image is twice the rotation angle of the prism. Dove prisms with metal coating can replace retroreflectors.
2.4 K9 roof prism
The roof prism can rotate and reverse the image and deflect light with a 90° bend. It is suitable for telescopes and any optical instruments that need to flip the image from the objective lens, open the right side, and bend at 91° to maintain the correct visual direction.
2.5 K9 corner prism
The corner reflector is used for collimation, allowing the incident light to return to the light source. The corner cube prism is a glass element used for retroreflecting. It retroreflects the incident beam with three 90° angles. The corner cube prism is a glass element used for retroreflecting. It retroreflects the incident beam with three 90° angles. The error of these glass angles must be within a few seconds of accuracy, but the incident surface can have an error of more than 5″ without significant impact on the performance of the corner cube.
2.6 K9 wedge prism
The wedge angle of the wedge prism and the anti-reflection coating on the back can reduce the interference of ghost images reflected on the back surface. The high-precision substrate ensures the accuracy of the reflected and transmitted light wavefront. Jingliang Optoelectronics provides a variety of wedge prisms, and the antireflection coatings include UV, VIS, NIR, SWIR.
