Short-wavelength pass filter
A shortpass filter is an optical filter designed to allow light below a certain wavelength to pass through while blocking longer wavelengths. Also known as a short-pass filter, its function is to filter out longer wavelength light (such as red light or infrared) and only let shorter wavelength light (such as ultraviolet or blue light) pass through. Shortpass filters are widely used in spectral analysis, laser systems, fluorescence microscopy, and various scientific experiments requiring specific wavelength light. Working Principle of Shortpass Filters Shortpass 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 above a certain wavelength to interfere and be reflected, while light below that wavelength…
Polarizing Beamsplitter
The VY Optics Polarizing Beam Splitter (PBS) is a high-precision optical component designed to separate light beams based on their polarization state. Our PBS efficiently divides incident light into two distinct beams: horizontally polarized light and vertically polarized light. This product finds extensive applications in laser systems, microscopes, optical communication, optical measurement, and quantum optics. Working Principle: The working principle of the VY Optics PBS is based on the polarization characteristics of light. When natural or partially polarized light strikes our PBS, horizontally polarized light (p-polarized light) passes through the splitter, while vertically polarized light (s-polarized light) is reflected. We employ advanced optical coatings and high-quality optical glass to ensure that the angles of transmitted and reflected light are orthogonal, thus achieving effective beam separation. Product Features: High Precision Separation:…
How does Band Pass Filter Work?
A band-pass filter or bandpass filter (BPF) is a device that passes frequencies within a certain range and rejects (attenuates) frequencies outside that range. Description of Band Pass Filter An example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit). These filters can also be created by combining a low-pass filter with a high-pass filter. Bandpass is an adjective that describes a type of filter or filtering process; it is to be distinguished from passband, which refers to the actual portion of affected spectrum. Hence, one might say “A dual bandpass filter has two passbands.” A bandpass signal is a signal containing a band of frequencies not adjacent to zero frequency, such as a signal that comes out of a bandpass filter. An ideal bandpass filter…
High Temperature Quartz Tube
How strong is quartz glass? Properties of Fused Silica/Quartz Glass Property Value General Density 2.23 Mechanical Design Tensile Strength 48 Design Compressive strength 1100 Young’s Modulus 72 What is quartz glass used for? Major applications of quartz glass products include both the lighting and the semiconductor industry. In the lighting products, quartz glass is widely used in high-temperature arc and filament lamps requiring high purity to minimize devitrification and provide optimum sag resistance. What temp does quartz glass melt? approximately 1600 °C, quartz melts at approximately 1600 °C forming a tacky liquid. In the course of melting, many silicon-oxygen bonds are broken. Can quartz be used to make glass? Quartz sand is used in the production of container glass, flat plate glass, specialty glass, and fiberglass. Is glass harder than…
Hole Inspection Lens for 360°
The hole inspection lenses for 360 inside view can easily inspect holes, cavities ,containers and threads, Unlike common optics or so-called “pinhole lenses” which can only image flat fields of view, hole inspection optics are specifically designed to image both the bottom of a hole and its vertical walls. It can be widely used in indutries of food, automobile, medicine VY Optoelectronics Co.,Ltd. produce and design kinds of optical lenses, such as infrared lens, imaging lens, industrial lens etc.. One of the hottest selling industrial lenses is HOLE INSPECTION LENS, we aim to disign a 360 degrees hole inspection lens which can image at both the inner walls and the bottom of the objects, the shape of the objects can be very different, such as threaded holes, cones, bottle caps, cylinders and so on. The hole…
Bandpass filter
A bandpass filter is an optical filter designed to transmit light within a specific wavelength range while blocking wavelengths outside that range. Its working principle involves either interference or absorption mechanisms to achieve selective transmission of specific wavelengths. Bandpass filters are widely used in spectral analysis, laser systems, fluorescence microscopy, optical communications, and various scientific experiments. Types of Bandpass Filters Narrowband Filters: These allow a very narrow range of wavelengths to pass through, typically from a few nanometers to several tens of nanometers. They are often used in applications requiring high selectivity and precision, such as laser wavelength selection and fluorescence detection. Wideband Filters: These allow a broader range of wavelengths to pass through, usually from tens of nanometers to several hundred nanometers. They are used in applications requiring higher…
