Cylindrical Microlens Array Product Features:

• We use photolithography and etching technology
• The materials are fused quartz and silicon. Fused quartz performs well in the range from UV to IR, and has high thermal and chemical stability, which is very suitable for the use of high-power lasers. Single crystal silicon has high transmittance in the infrared and high thermal conductivity, which is very suitable for applications from near-infrared to infrared.
• Our standard cylindrical microlens array hosts array sizes ranging from a few rows and columns to large-area arrays.
• The standard cylindrical microlens array lens subunit aperture ranges from 25um to 1000 microns, which can meet different needs from microstructure imaging to high-power shaping
• Effective teaching aids range from 0.04mm to 200mm, which can meet both short-range imaging and long-range collimation needs.
• Multiple wavelength designs, classic wavelengths 632.8nm, 970nm, 1550nm, 405nm, 976nm, 800nm, 532nm, 308nm, from UV 0.308um to 1.55um bands, there are off-the-shelf products, which can support multiple spectral systems from UV/VIS/NIR/IR
• We support flexible customization services, size, focal length, wavelength, array arrangement, etc. can be customized according to customer needs

How to customize cylindrical microlens arrays

• To customize cylindrical microlens arrays, the most important thing is to clarify the sub-lens pitch, focal length, design wavelength, material and array arrangement size.
• We can support the customization of the following parameters:
  Material options: fused silica, silicon
• Sub-unit diameter: 10um-1500um
• Focal length or curvature radius: provided according to requirements
  Operating wavelength: single wavelength or broadband AR anti-reflection film in the range of 200nm-20um
• Optical axis/mechanical alignment accuracy: <1um

 

Cylindrical Microlens Arrays Applications:

• Homogenization and collimation of beams in one direction
  In high-power laser or LED lighting, cylindrical microlens arrays can homogenize or collimate the beam in one dimension to form a uniform strip spot or collimated straight beam, improving the consistency of the beam
• Line marking
  Cylindrical microlens arrays can transform point-shaped lasers into a thin, clear light line, so that they can be automatically aligned, centered, and guide line cut in the marking system to assist in surface detection
• Beam shaping
  Cylindrical microlens arrays can linearly expand and linearly homogenize Gaussian beams to achieve controllable spot shapes, such as linear, square, or uniform bands, which are particularly suitable for picosecond/nanosecond laser processing
• Collimation in the slow axis direction of semiconductor lasers
  Cylindrical microlens arrays can collimate the divergence angle of semiconductor lasers on the slow axis, compress the beam in the slow axis direction, and form a collimated straight beam, which can improve the output efficiency of the laser module
