Fluorescent filters, also known as fluorescent filters, are widely used in various fields. Its main function is to separate and select the excitation and emission spectra of substances. Fluorescent filters typically use a transparent glass substrate and are coated on both surfaces. The thickness of the anti reflection film will be selected as an integer multiple of half the wavelength, at which point the reflection superposition will be enhanced. The anti reflection thickness is a multiple of a quarter wavelength, and the superposition is enhanced at this time. Fluorescent filters include various types of fluorescent filters, typically
The optical part that separates a laser beam into emitted and reflected light using transparent optical elements is called a beam splitter, where the ratio of emitted light to reflected light is 1:1, known as a half mirror. There are two types of spectrometers: cubes and tablets. Regarding the amount of light split, half mirrors are designed based on a 1:1 ratio of reflected and transmitted light. Due to the different incident directions or polarization states of the incident light, the ratio of light is sometimes less than 1:1. Reflection and transmission characteristics vary with the direction of incident light:
In daily life, we can see various colors of objects. There are also many colors for color filters, such as red, orange, yellow, green, blue, purple, etc. So what determines the color of the filter? Let's first clarify the principle of light. What is the difference in the principle of light shining on transparent and opaque objects. One The color of opaque objects is determined by the reflected color light. The color of opaque objects (such as tables and walls) is determined by the color light reflected by them,
When a laser cutting machine cuts metal materials, a large amount of gas, slag, and splashes are released from the working surface. Maintaining the lens is used to prevent damage to the aggregated lens during the cutting process. Of course, it is not only used for laser cutting machines, but also for laser welding, marking, engraving and other laser equipment, so the market for maintaining lenses is very strong. On the back of strong market demand, there are generally uneven product prices and quality. How many maintenance lenses are available on the market
The so-called narrowband filter is a subdivision of the bandpass filter, and its definition is the same as that of the bandpass filter. This type of filter allows light signals to pass through a specific band, while blocking light signals on both sides outside of this band. The passband of a narrowband filter is relatively narrow, generally less than 5% of the center wavelength value. Parameter description of narrowband filter: The center wavelength of narrowband filter is generally the operating wavelength of the instrument or equipment, which refers to
Reflective lenses are important components in optical experiments, and their quality, performance, and durability have a significant impact on success. Our company offers a variety of different reflective mirror products to ensure that customers can find products that are suitable for their applications. When choosing a reflector, it is important to consider parameters such as reflectivity, wavelength range, laser damage threshold, and durability of the coating. We have long-term inventory of many common models of lenses to achieve fast supply. Coated broadband metal coated metal
The full name of OLPF optical low-pass filter is Optical low-pass filter, which is mainly used to filter different frequency wavelength optical signals in the input light, transmit them to CCD, and avoid interference of different frequency signals on CCD's color interpretation. OLPF has a significant impact on the control of false colors, which mainly come from dense colors
With the development of optical technology, there is an increasing demand for precision optical coating, such as ultrafast laser optical components and special laser optical components, which have very high requirements for coating. Generally speaking, the price and quality of substrates depend on the material, shape, size, tolerance, and polishing quality. The first step in material selection is usually to determine the material of the substrate, which should ideally have high transmittance for all wavelengths and almost no absorption. If it is not transmissive, low cost can be used

The so-called spectroscope is actually a semi transparent and semi reflective glass. When light shines on the spectroscope, half of the light will pass through the spectroscope and half of the light will be reflected out. The simple model of "semi transparent and semi reflective glass" is to take an ordinary but very thin mirror and drill many small holes evenly on it, so that the total area of the holes reaches half of the original mirror surface area. This is semi transparent and semi reflective glass! Of course, the actual process is not that complicated, but the principle is like this. spectroscopy
