利用透明光学元件将激光束分为发射和反射光的光学部分，称为分光镜，其中发射光与反射光之比为1:1，称为半反射镜。 分光镜有两种:立方体和片剂 关于分束的光量： 半反射镜是根据1：1反射和透射光的比例设计的。由于入射光的入射方向或偏振态的不同，光的比例有时小于1：1。 反射和透射特性随入射光方向变化：
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 high-end real-time fluorescence quantitative PCR instrument is mainly suitable for real-time detection of the PCR process through fluorescence signals during PCR amplification. Has advantages such as high noise to noise ratio, deep background, and low crosstalk. Standard size: ex - dia 12.5mm * 5mm em - dia 12.5mm * 5mm dm -18 * 12.7 * 1.05mm size can also be customized, phone communication to discuss Rui
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
At a certain angle, a dichroic mirror is typically used to split a beam of light into two different directions of spectral light. The commonly used fluorescence microscope is an elongated dichroic mirror, which reflects the excitation light and fluorescence light transmission ratio in the fluorescence principle diagram. The dichroic mirror also uses stage filters for fluorescence microscope illumination equipment and projectors. A multi bandpass filter is a single filter with multiple bandpass filters, which is our company's most distinctive and competitive product. The manufacturing of multi bandpass filters requires high technology and high transparency
