Direct answer
What Is This Multi-Material Square and Cylindrical Optical Lens?
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.
Compact Square Optics
Square and rectangular formats fit compact spectroscopy, laser diode and multi-channel detection layouts.
Drawing-Based Customization
Length, aperture, focal length, edge finish and coating can be reviewed from the buyer's drawing.

Material selection
BK7/K9, Fused Silica, Sapphire and CaF2 Transmission Choices
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.
BK7/K9 Optical Glass
Often selected for visible and near-infrared applications where cost, clarity and availability matter.
Fused Silica
Reviewed for UV laser compatibility, low thermal expansion and stable optical performance.
Sapphire and CaF2
Sapphire supports hard-use environments, while CaF2 is considered for deep UV to mid-infrared spectroscopy.
Lens form
Square Flat Lens and Cylindrical Rod Lens Design Options
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.
- Square lens: useful for compact UV-Vis-NIR modules, multi-channel spectrometers and sensor assemblies.
- Cylindrical plano-convex lens: supports line beam forming, scanning and metrology layouts.
- Cylindrical plano-concave lens: can expand one axis of the beam when the optical path requires controlled divergence.

How to Choose the Right Lens Material Without Over-Specifying
Start With Wavelength
Choose BK7/K9 for many visible-NIR tasks, fused silica for UV stability, sapphire for durability and CaF2 for infrared spectroscopy.
Confirm Beam Function
Use square forms for compact modules and cylindrical forms when one-axis line shaping or focusing is needed.
Define Coating Target
Specify laser wavelength, angle of incidence and throughput goal before coating selection.
Buyer FAQ
FAQ About Multi-Material Square and Cylindrical Optical Lenses
How should I choose between BK7, fused silica, sapphire and CaF2?
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.
What is the difference between square and cylindrical lenses?
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.
Can AR coating be matched to laser diode wavelengths?
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.
Do you support mixed-material samples?
Single-material samples and mixed-substrate batches can be reviewed, with inspection matched to the drawing and operating wavelength.
