Custom Micro Miniature Lenses Product Discription
Micro-miniature lenses are precision optical components with optical diameters as small as 0.35 mm, suitable for applications such as high-definition endoscopic imaging and laser beam focusing. Asin Optics is a manufacturer of micro-lenses; we offer customization based on your blueprints or concepts—covering focal length, field of view, numerical aperture (NA), shape, operating wavelength coatings, and lens type—while ensuring consistent quality from prototype to mass production.
Core Features Of Our Micro Miniature Lenses
- We offer custom small-diameter lenses with diameters as small as 0.35mm and radii of curvature (R-values) starting at 0.4mm.
- Our current product range includes miniature convex, concave, and meniscus lenses, as well as micro-aspherical and micro-cylindrical lenses.
- We utilize precision molding, cold processing (grinding and polishing), and aspheric machining technologies to achieve sub-micron level precision.
- We provide various coating options, including broadband anti-reflective (AR) coatings, beam-splitting coatings, and laser-damage-resistant coatings.
- We operate a dedicated production line for rapid prototyping of micro-optical components, typically delivering samples within 2–4 weeks and ensuring a seamless transition to consistent mass production.

Mico Minature Lenses Applications
Medical Endoscopes
Medical endoscopes offer very limited space for lenses; standard lenses cannot fit, necessitating the use of high-precision, small-diameter lenses. As a supplier of micro-lenses for endoscopes, we can reduce the outer diameter of the lens assembly to under 1.6 mm, thereby freeing up more space for working channels and illumination fibers.
Fiber Optic Coupling
In laser medical devices, fiber-optic sensing, and optical communication systems, conventional spherical lenses suffer from significant spherical aberration, preventing light from focusing to the diffraction limit and resulting in poor coupling efficiency. Custom micro-lenses designed for fiber coupling can be optimized for specific laser wavelengths to minimize aberrations.
Micro Laser Modules
Applications such as line LiDAR, structured-light 3D scanning, micro-projection, and laser pointers require shaping the elliptical, astigmatic beam emitted by a laser diode into sharp lines, points, or uniform area patterns. As a manufacturer of custom micro-optics, we design beam-shaping optical paths from the source, creating micro-lens assemblies that incorporate aspheric fast- and slow-axis collimators, Powell lenses, or diffractive optical elements (DOEs). By precisely controlling beam divergence, line width, and depth of focus, we can deliver the specific beam profile you require.
Optical Sensors
Applications such as NDIR gas sensors for environmental monitoring, medical fluorescence immunoassays, and colorimetric sensors require tiny lenses to collect weak signal light and efficiently transmit it to the photosensitive surface of a detector. A high-precision, small-diameter lens can collect fluorescence or absorption light at specific wavelengths and collimate it onto a photodetector, thereby enhancing the signal-to-noise ratio.
