Scientists convert infrared rays to blue light for sterilization
OSAKA, Japan, June 25, 2021 — A microcavity device that converts infrared (IR) radiation into blue light could enable safe, daily use of deep ultraviolet (DUV) light for disinfection and sterilization. The device was developed by a search group from Osaka University and was built without a polarity-inverted structure. the shortage of reliance on birefringence or the periodically polarization inverted structure expands the pliability within the selection of the device structures and therefore the materials — giving the researchers more flexibility within the selection of structures and materials for the wavelength conversion to convert to DUV light. A DUV wavelength range of 220 to 230 nm is desirable if DUV light is to be used safely as a disinfectant. Although wavelength conversion offers a possible solution to achieving this as-yet-unrealized…

Long-wavelength pass filter
A longpass filter is an optical filter designed to allow light above a certain wavelength to pass through while blocking shorter wavelengths. Also known as a long-pass filter, its function is to filter out shorter wavelength light (such as ultraviolet or blue light) and only let longer wavelength light (such as red light or infrared) pass through. Longpass filters are widely used in fluorescence microscopy, spectral analysis, laser systems, and various scientific experiments requiring specific wavelength light. Working Principle of Longpass Filters Longpass filters are primarily manufactured using interference coating technology. Multiple layers of optical thin films are coated on a substrate, with their thickness and refractive indices precisely designed and controlled. This design causes light below a certain wavelength to interfere and be reflected, while light above that wavelength…
Introducing Industrial Inner Wall Inspection Lens 360°
Introducing the Upgraded Industrial Inspection Lens We are excited to announce the latest enhancements to our “Industrial Inner Wall Inspection Lens”, designed specifically for Industrial Inspection and high-precision applications. The upgraded High-Resolution Inspection Lens has significant improvements in aperture, length, and focal length, providing a great inspection effect. Explain the main upgrade changes about our High-Resolution Inspection lens. Aperture is Changed from 8.5mm to 11mm The main impact about increasing the aperture size from 8.5mm to 11mm, that means we can get a wider Field of View. A larger aperture allows more light to enter Optical Inspection Lens, which can improve the image quality in low-light conditions and potentially reach a Wide-Angle Inspection Lens. This change can be beneficial for applications requiring clear images in darker environments or wider area…
Optical Prisms
In the modern field of optics, optical prisms are essential optical components that play a crucial role in various fields such as science, engineering, and medicine. This article will delve into the principles, classification, applications, and manufacturing processes of optical prisms, providing readers with comprehensive insights. Principles of Optical Prisms Optical prisms utilize their unique geometric shapes and optical properties to alter the propagation direction of light, primarily based on principles such as refraction, total internal reflection, and dispersion. Refraction: When light propagates from one medium to another, it undergoes refraction. Optical prisms exploit this phenomenon to deflect light rays, achieving light separation and directional propagation. Total Internal Reflection: If the angle of incidence exceeds the critical angle when light propagates from a medium to a lower refractive index medium,…
