Unpolarized dichroic cross prism
By not relying on polarization, it is possible to simultaneously combine and spectrally separate any wavelength range, eliminating the need for a projector's illumination space and achieving compactness. Shortening the optical path further enhances brightness, contributes to energy savings, and expands the design flexibility of our lenses.

N-BK7 right-angle prism optimized for 90° deviation angle. All products are sold individually as standard items. We offer quick delivery due to complete stock availability.
The right-angle prism functions to bend the light path by 90° when light is incident vertically. The image obtained through a single prism is upright, but laterally inverted. By using two prisms simultaneously, it is possible to convert the laterally inverted image from one prism into an upright image. It is effective in improving the transmittance at the incident and exit surfaces and reducing the occurrence of ghost images. ■ Optimized for 90° deflection ■ Forms an upright laterally inverted image ■ Available with aluminum coating (on the reflective surface) and anti-reflective coating (on the incident and exit surfaces) * You can download the catalog from Edmund Optics Japan, which features this product, from the link below.

Made of UV-grade synthetic quartz. Usable at high temperatures. All products are sold individually as standard items. We offer short delivery times due to complete stock availability.
Prisms made from UV-grade synthetic fused silica have particularly excellent transmission properties in the ultraviolet wavelength range. Additionally, due to their low thermal expansion coefficient, they are ideal for use at high temperatures. The TECHSPEC λ/10 high-precision right-angle prisms made of synthetic quartz are available in two types: one with an aluminum metal coating on the prism's sloped surface (reflective surface) and one without. The aluminum coating is protected by an Inconel layer and a black coating. Furthermore, prisms with this coating feature specific anti-reflective coatings (UV-VIS multi) on both the incident and exit surfaces. This effectively improves transmission rates at the incident and exit surfaces and reduces ghost image formation. *You can download the catalog from Edmund Optics Japan, which features this product, from the link below.

A unique prism that can rotate the image obtained from the exit surface by twice the rotation angle of the prism. Available with or without coating.
The TECHSPEC double prism, when rotated around its long axis, produces an image from the exit surface that rotates twice the angle of rotation. For example, if the prism is rotated 90°, the image is inverted by 180°. You can choose between a type with VIS 0° multi-AR coating applied to both the incident and exit surfaces, and an uncoated type without any coating. The VIS 0° multi-coating maximizes transmission efficiency in the visible range. It is designed to provide an optimal image without chromatic aberration when light is incident in parallel. The top surface of the prism has a sanded finish. Note that there is no beveling on the edge of dimension B. ■ Functions as a displacement reflection prism and double prism depending on the presence of coating ■ Functions as a double prism that acts as an image rotator to rotate the image ■ A displacement reflection prism with a 360° constant angle that shifts the optical axis parallel and returns it to the original direction *You can download the catalog from Edmund Optics Japan from the link below.
A retroreflective prism that functions as a dispersive prism or a 60° angle prism.
This is a prism with angles of 30°, 60°, and 90°. Depending on whether it has an aluminum coating on the base, it functions as a dispersive prism or a deflecting prism. ■ The coated prism functions as a 60° deflecting prism. ■ The uncoated prism functions as a dispersive prism. ■ The coated prism is also ideal for retroreflective arrangements. ■ No image inversion. *You can download the catalog from Edmund Optics Japan below.

Anamorphic prisms are used to enlarge the size of a laser beam in one axial direction. They are ideal for expanding only one direction (the short axis direction) of the elliptical beam emitted from a typical laser diode, transforming it into a shape that is nearly circular. Composed of two identical prisms, they can achieve an aspect ratio enlargement from 2:1 to 6:1 by placing the prisms in a specified positional relationship to each other. The anti-reflective coatings applied to the entrance and exit surfaces of the prisms offer two options. The NIR I multi-coating functions over a wide wavelength range of 600 to 1050 nm, providing excellent performance with red semiconductor lasers such as 635 nm and 670 nm. In contrast, the coating for 405 nm uses a V-coating optimized for blue-violet lasers. *You can download the catalog from Edmund Optics Japan that features this product from the link below.

The video we took with such effort is too valuable to be used only for education.
Have you ever felt that even though you created video manuals, they only ended up being used for education? In recent years, the use of video manuals for educational purposes has become very widespread, but Time Prism is not just a tool for creating video manuals. Time Prism allows you to record work processes on video and utilize them as procedure manuals and educational materials. Moreover, based on those videos, it can help you understand differences and variations in work time, leading to improvements in work processes. It is recommended for companies that want to consider initiatives such as video manual creation, skill inheritance, and work improvement not as separate efforts but as a continuous flow. This document does not provide a detailed introduction to all the features of Time Prism; rather, it is an overview that highlights the presence of both educational and improvement functions. The content is designed to be read quickly, so please feel free to take a look!

![[Case Study] Proposal for a prism that maintains high reflectivity even when dirt adheres.](https://image.mono.ipros.com/public/product/image/a1e/2000722501/IPROS47839255223519359026.png?w=280&h=280)
Achieve nanometer-level precision in optical components! Realize high reflectivity unaffected by surface conditions!
We received a request from a semiconductor manufacturer to analyze samples of prisms used in integrated circuit manufacturing equipment sensors. Upon conducting an analysis with our own application of grease (contamination), we discovered that the contamination disrupted the total reflection conditions, resulting in a loss of light intensity. In the event that contamination occurs, it could lead to a decrease in detection accuracy and potentially cause process defects, making prompt improvements essential. Therefore, we proposed a prism equipped with a high-reflective mirror that maintains high reflectivity even if contamination occurs, referred to as the "Prism with Induced Multi-Layer Film Mirror." We received high praise from the semiconductor manufacturer, and it was adopted immediately. [Case Overview] ■ Issue: Contamination on the reflective surface affects and reduces reflectivity ■ Solution: Maintains high reflectivity even with contamination, contributing to the quality assurance of precise semiconductor manufacturing ■ Featured Product: Prism *For more details, please refer to the PDF document or feel free to contact us.
