Products
Yutai Optics provides core optical components and solutions for the biometric identification industry. Our products serve as the foundation for a wide range of high-end biometric devices, enabling accurate and fast identification.
In the field of fingerprint recognition, our company produces micro optical lenses and micro optical prisms, which are key components in optical fingerprint modules. They ensure uniform and distortion-free fingerprint image capture. For facial recognition, we supply high quality near-infrared filters that effectively block visible light interference, ensuring precise imaging in complex lighting conditions. Moreover, our optical components are widely used in iris recognition imaging systems. Their high transmittance and low distortion characteristics guarantee high security and accuracy in identity authentication.
Products from Yutai Optics are known for their excellent stability, consistency, and environmental adaptability. They are widely used in applications such as security, access control, mobile payment, and smart devices, providing reliable hardware support for the protection of personal information and data security.
Infrared Optical Filter Bandpass Infrared Filter IR Cut Off Filter
Longpass Filters, also known as Longpass Edge Filters, are designed to transmit wavelengths greater than the cut-on wavelength of the filter.
Due to its selective absorption in visible wavelength range, color glass filter will exhibit various color depending the glass type.
The nd data of H-K9L is 1.5168, vd data is 64.20. H-K9L is the alternative for N-BK7. H-K9L (N-BK7) is a RoHS-compliant borosilicate crown glass.
Optical IR MgF2CaF2 Crystal Window
Low iron glass also has all the processability of high-quality float glass, has excellent physical, mechanical and optical properties, and can be processed in a variety of deep processing like other high-quality float glass.
Optical Spherical Singlet Lenses
Yutai’s N-BK7(H-K9L) plano-convex lenses are available uncoated or with a variety of antireflection coatings.
An achromatic lens is a lens that is designed to limit the effects of chromatic and spherical aberration,and is corrected to bring two wavelengths (typically red and blue) into focus on the same plane.
