Felix Glass Co., Limited supplies custom square optical lenses and cylindrical rod lenses for laser diode beam collimation, one-dimensional beam shaping, spectral detection modules, laboratory instruments and optical assemblies. The original product focus is retained: BK7/K9, fused silica, sapphire and calcium fluoride material options, custom square or cylindrical lens shapes, UV-to-IR transmission choices and wavelength-matched AR coating.
For buyers comparing lens and prism-category components, this page organizes the same technical information into a clearer engineering review path: material selection, lens form, transmission range, surface quality, coating, applications, manufacturing and RFQ details.


It is a custom optical lens family made in square flat and cylindrical rod forms. Square flat lenses are used as compact focusing, collimating or protective optical elements in spectral modules. Cylindrical lenses focus or spread light in one axis, helping convert a laser diode beam into a line profile for scanning, metrology or inspection systems.
Cylindrical plano-convex or plano-concave forms support line beam shaping and single-axis focusing.
Square and rectangular formats fit compact spectroscopy, laser diode and multi-channel detection layouts.
Length, aperture, focal length, edge finish and coating can be reviewed from the buyer's drawing.
The original specification content is preserved and organized for faster review by US purchasing, engineering and optical design teams.

Material choice should follow wavelength range, laser power, environment, durability and budget target. Felix Glass can help review the practical substrate based on the operating band and mechanical conditions.

Often selected for visible and near-infrared applications where cost, clarity and availability matter.

Reviewed for UV laser compatibility, low thermal expansion and stable optical performance.

Sapphire supports hard-use environments, while CaF2 is considered for deep UV to mid-infrared spectroscopy.

Square flat lenses can serve compact spectral detection modules as a collimating, focusing or optical interface element. Cylindrical rod lenses provide one-dimensional focusing or divergence, helping form a uniform laser line from a diode source.
BK7/K9, fused silica, sapphire and CaF2 cover visible, UV, near-infrared and selected mid-infrared use cases.
Square flat and cylindrical rod forms help fit compact instruments and line-beam laser modules.
Surface quality, flatness and beam uniformity can be controlled to match the assembly requirement.
AR coating can be reviewed for laser diode wavelengths and spectral throughput goals.
The original application scope is retained and grouped by how buyers usually evaluate the part inside an optical system.
Used for beam collimation, line forming and controlled one-axis focusing.
Material choice can support UV-Vis-NIR and FTIR-related instrument designs.
Custom apertures and coatings help fit measuring instruments and detection assemblies.
Square and cylindrical formats can be reviewed for compact spectral imaging equipment.
Felix Glass supports multi-material blank cutting, cylindrical CNC grinding, square flat polishing, wavelength-matched AR coating, edge chamfering, black edge treatment, spectral transmittance testing and beam uniformity inspection. Prototype samples, small batches and repeat production can be reviewed from drawing and quantity requirements.
Select BK7/K9, fused silica, sapphire or CaF2 by wavelength and environment.
Cut, grind and polish square, rectangular or cylindrical lens geometry.
Apply AR coating as required, then inspect dimensions, surface and optical performance.

Choose BK7/K9 for many visible-NIR tasks, fused silica for UV stability, sapphire for durability and CaF2 for infrared spectroscopy.
Use square forms for compact modules and cylindrical forms when one-axis line shaping or focusing is needed.
Specify laser wavelength, angle of incidence and throughput goal before coating selection.
BK7/K9 is practical for many visible and NIR systems, fused silica is often reviewed for UV lasers, sapphire is chosen for hard-use environments, and CaF2 is reviewed for deep UV or mid-infrared spectroscopy.
A square lens works as a compact flat optical element, while a cylindrical lens focuses or expands light in one axis to form or control a laser line.
Yes. Coating can be reviewed for common diode wavelengths such as 405 nm, 450 nm, 520 nm, 635 nm, 808 nm and 905 nm, along with other project-specific bands.
Single-material samples and mixed-substrate batches can be reviewed, with inspection matched to the drawing and operating wavelength.
