Optical filters have become the core optical components of modern medical equipment and scientific research instruments.
By accurately separating target wavelengths and suppressing the infection of background light and stray light. In the field of life sciences, light is one of the core technologies for exploring the mysteries of life and precise diagnosis and treatment.
We have been professionally cultivating optical thin film coating technology since 2015. Based on the full-band coating capability from EUV to 30000nm, focusing on ultraviolet, visible light and near-infrared light, combining precision coating technology and customized design, we provide high-performance filter solutions for the global biomedical industry.
To know more about our production capability
What we can do:
Ultra-narrowband bandpass filter
We use a coating technology that combines ion beam sputtering coating and ion-assisted coating to achieve a bandwidth as narrow as 0.5nm, a transmittance of >95%, and an edge steepness of <1%.
Single band to multi band fluorescence filters
We have successfully developed multi-band filters with multiple channels. Based on multiple channels, combined with high transmittance and deep cutoff depth, multiple fluorophores can be detected simultaneously and efficiently.
Choose ultra-low autofluorescence substrate
We generally use fused quartz as the substrate of the filter. The autofluorescence intensity of fused quartz itself is very low. With excellent surface shape and parallelism standards, it can greatly reduce the interference of background noise
Excellent cut-off depth
Our existing fluorescence filter standards can achieve a cut-off depth OD>7 from ultraviolet to near infrared. Such a deep cut-off depth almost filters out all background stray light, making the background of the research target dark and deep.
Ultra-long service life
The coating technologies we use, ion beam sputtering coating and ion-assisted coating, are both hard coating methods. After hard coating, the filter has extremely high durability and can withstand the test of various environmental changes.
