Application of Fluorescence Microscope Filter
Filter is widely used in fluorescence microscopes, so many filter designs are determined according to the requirements of microscope manufacturers. Users can place orders based on the model of the sample in use and choose the same or similar filter model from the standard models. Fluorescence filters are widely used in high-precision precision optical equipment, laser processing equipment, measuring instruments, as well as medical beauty, photography equipment, machine vision and other fields. There is no standard size for filters. However, the most common size is a circular shape with a diameter of 25mm. In addition, commonly used sizes include 25.5x36mm and 26x38mm. Ruicheng Optoelectronics can customize the size of the filter according to the actual needs of customers.
The function of the filter slider is to provide excellent parallelism and consistency to ensure the consistency of fluorescence excitation. Filter products are mainly classified according to spectral bands, spectral characteristics, thin film materials, application characteristics, etc. Filters are made of special dyes or optical films deposited on the surface of plastic or glass substrates to attenuate (absorb) some light waves or precisely select a small range of light to pass through, and reflect (or absorb) other unwanted bands.
The differences between fluorescence microscope filters can be studied from the following aspects:
1. Production process. The manufacturing process of the filter has a significant impact on the quality of the filter. The quality of the process directly affects the service life and accuracy of the product. As often said, it is good to see the level of rigor in her manufacturing process.
2. Film layer error. Only good equipment can produce good products. Ruicheng Optoelectronics has an imported vacuum coating machine that can effectively control coating errors. Of course, poor coating can cause small or large errors, which cannot be ignored.
3. Product materials. Good filtering materials can make people feel special and comfortable in terms of texture and visual appeal, so the choice of materials is very important.
4. Coating coverage. The larger the coverage area, the better. Of course, we have over 98% coverage.
5. Surface smoothness. No matter what it is, it has its own standards, so the surface smoothness also has its own standards. The specific standards are still based on the filter itself, which is difficult to distinguish from the naked eye and requires professional machines for inspection.
