The 940nm wavelength sits in the optimal near-infrared range for machine vision applications, providing excellent penetration through various materials while maintaining high contrast and signal clarity. This makes it ideal for applications requiring consistent performance regardless of ambient lighting conditions.
- 90% Peak Transmission: Maximize light throughput for brighter, clearer imaging
- OD3 Blocking (200-1100nm): Eliminate unwanted wavelengths that could compromise system accuracy
- 25nm FWHM: Precise spectral control for consistent, repeatable results
Ideal Machine Vision Applications:
- Fingerprint Recognition Systems Enhance biometric security systems with superior contrast and detail capture. The 940nm wavelength penetrates skin surface irregularities while highlighting ridge patterns for more accurate identification.
- IR Sensing Applications Perfect for proximity sensors, gesture recognition, and object detection systems. Provides reliable performance in varying environmental conditions while filtering out visible light interference.
- Night Vision Systems Enable clear imaging in low-light conditions without visible illumination. Ideal for security cameras, automotive night vision, and surveillance applications where covert operation is essential.

Optical dicing refers to precision cutting processes used to segment optical materials, particularly those with specialized coatings, into smaller functional components while maintaining their structural and optical integrity. In the context of optical coating flats (flat substrates like glass, fused silica, or semiconductors coated with anti-reflective, dielectric, or other optical layers), dicing ensures these coated substrates meet exact dimensional requirements for applications in photonics, lasers, sensors, and semiconductor devices.
Methods
- Saw Dicing: Diamond-coated blades for clean cuts with minimal chipping.
- Laser Dicing: Non-contact ablation for delicate or brittle materials, reducing mechanical stress.
- Plasma Dicing: Dry etching for ultra-fine features, ideal for advanced semiconductor wafers.
Price
Dicing Service will generally cost from $50 to $125 per piece. Depending on the accuracy and size you are requesting.
