Description
Precision Plano Concave Lens
Precision plano-concave lenses are negative focal length optical lenses designed to diverge incident light while maintaining controlled optical performance. Jiujon Optics manufactures precision plano concave lenses and double concave lenses for laser systems, imaging equipment, measurement instruments, machine vision, and other optical applications.
These lenses feature one flat surface and one concave surface, providing negative optical power and controlled beam divergence. They are suitable for applications where a divergent optical path is required, including beam expansion, optical alignment, laser systems, imaging assemblies, and compact optical instruments.
Jiujon Optics provides customized plano concave lenses according to the requirements of different optical systems. Material selection, diameter, center thickness, radius, surface quality, dimensional tolerance, and optical coating can be specified according to the application.

Double Concave Lens Options
In addition to precision plano-concave lenses, Jiujon Optics can manufacture double concave lenses with two concave optical surfaces. Double concave lenses provide negative optical power and are commonly used when a symmetric diverging lens configuration is required.
The choice between a plano concave lens and a double concave lens depends on the optical design, required focal length, available installation space, beam geometry, and system performance. Our engineering team can manufacture customized optical components based on drawings, specifications, or application requirements.
Optical Materials and Coatings
The optical material can be selected according to the operating wavelength and environmental requirements. Common material options include N-BK7 and fused silica, while other optical glass materials can be considered for specific applications.
Anti-reflective coatings can also be applied to improve transmission and reduce surface reflection. Coating specifications can be customized for different wavelength ranges, including visible and selected near-infrared applications.
Applications of Precision Plano Concave Lenses
Precision plano concave lenses are used in a wide range of optical systems where controlled beam divergence or negative optical power is required.
Typical applications include:
- Laser beam divergence and beam conditioning
- Optical imaging systems
- Machine vision equipment
- Optical measurement instruments
