Negative cylinders lenses
Plano-Concave (PCV) cylindrical lens belongs to the negative cylindrical lens category, featuring one plano surface and one concave surface, with a negative focal length. This lens is used for diverging collimated light in a single axial direction, particularly suitable for image one-dimensional compression, laser line generation, and anamorphic beam shaping.
Core Optical Functions
This lens achieves directional beam diffusion through its concave cylindrical surface, effectively correcting astigmatism and lenses distortion in optical systems. In laser focusing applications, it is often paired with plano-convex lenses for beam shaping, such as transforming circular spots into highly uniform linear spots; in projection display systems, it compensates for edge distortion, enhancing image geometric accuracy. Coating options support multi-band adaptation.
Deep Exploration of Diverse Application Scenarios
Industrial Inspection & Automation
In production line quality control, this lens is integrated into the beam shaping unit of 3D scanners to convert point sources into linear light strips, enabling high-speed capture of object contours. In semiconductor inspection equipment, it works in tandem with line scan cameras to provide uniform illumination fields for wafer surface defect identification. Laser marking systems modulate spot shapes using this lens to adapt to curved workpiece marking requirements.
Display & Imaging Technology
Laser projection equipment utilizes this lens to correct image edge distortion, solving trapezoidal distortion issues in short-throw projection. In emerging augmented reality (AR) glasses' optical engine modules, this lens compresses the beam divergence angle, optimizing the edge sharpness of virtual images. Furthermore, in medical endoscopic imaging systems, it compensates for the field curvature of fiber optic image bundles, enhancing lesion observation clarity.
Scientific Research & Biological Instruments
Flow cytometers employ this lens to diffuse laser diode beams, generating flat light spots to improve cell detection sensitivity. In the optical path of confocal microscopes, it corrects astigmatism induced by scanning mirrors, ensuring high-resolution imaging. Optical tweezers systems utilize this lens to modulate optical trap shapes, enabling non-contact manipulation of multiple particles.
Sensing & Information Processing
High-speed barcode readers expand laser scan line width using this lens, improving recognition rates in complex packaging scenarios. In spectral analysis equipment, it corrects optical axis deviation caused by grating diffraction, guaranteeing multi-channel data acquisition accuracy. Industrial-grade laser rangefinder sensors optimize the emission light field distribution using this lens, enhancing the signal-to-noise ratio for long-distance measurements.
