H.E. round waveguide

H.E. round waveguide

Accumulation of years of processing technology! Manufactured with the same dimensions as the flange diameter, maintaining high characteristics.

We would like to introduce our product, the "H.E. Round Waveguide." This product offers very high performance due to the absence of reflective surfaces. The internal cross-sectional shape of the tube is made to the same dimensions as the flange diameter, allowing for the maintenance of high performance. Additionally, when attempting to create such round shapes, the tube typically gets crushed and the dimensions change. However, thanks to our years of accumulated processing technology, we are able to produce it with high precision. 【Materials】 ■ Copper ■ Brass ■ Aluminum *For more details, please refer to the related links or feel free to contact us.

[Consultation Case for Metal 3D Printing] Special Waveguide Production Part 2

[Consultation Case for Metal 3D Printing] Special Waveguide Production Part 2

We have responded to requests to increase the size and change the shape from the previous prototype!

I would like to introduce a case where an associate professor from a national research institute conducting research on electromagnetic waves consulted us about the need for a waveguide to accurately and uniformly transmit fine electromagnetic waves. There was a request to "increase the size and change the shape from the previous prototype," and we verified the optimization of the internal cavity through preliminary prototyping. We also addressed surface treatment by implementing chemical polishing based on the results from the previous prototype. As a result, we were able to achieve the desired size and shape, and we were able to manufacture additional components within the budget. [Case Overview (Partial)] ■ Issue - A waveguide (a metal pipe that transmits electromagnetic waves) is needed to accurately and uniformly transmit fine electromagnetic waves. ■ Request - To increase the size and change the shape from the previous prototype. *Details of the case can be viewed through the related links. For more information, please feel free to contact us.

List of Bandpass Filters

List of Bandpass Filters

Short delivery time with stock sales! All items available for sale from one piece.

Edmund Optics offers a wide range of optical bandpass filters with a variety of bandwidth options. Laser line filters generally have a narrow bandwidth of 2 to 5 nm and are used for demanding laser applications. Fluorescence filters are designed to maximize energy transmission of the excitation and emission bands, typically having a wide bandwidth of 20 to 70 nm. Edmund Optics' 10 nm filters are suitable for chemical, environmental, and elemental analysis. Hard-coated filters achieve high performance with excellent durability. Soft-coated filters, manufactured using traditional vacuum deposition methods, are a suitable choice when cost is a concern. It is important to note that the optical characteristics of optical bandpass filters can vary significantly with the angle of incidence, so care should be taken when fixing or mounting them in optical systems. For more details, please visit the official Edmund Optics website via the link below.

Optical thin film products 940nm bandpass filter

Optical thin film products 940nm bandpass filter

A bandpass filter that selectively transmits near-infrared light at 940nm!

The 940nm bandpass filter is a bandpass filter that selectively transmits near-infrared light at 940nm. It has spectral characteristics that minimize the transmission (and maximize the reflection) of visible light and some infrared light. The film is formed using ion-assisted deposition (IAD), resulting in a shift-free and dense film. For more details, please contact us or refer to the catalog.
