Product Description
- Optical element material: UV fused silica
- High-reflectivity chromium coating
- Commonly used in imaging system eyepieces
LBTEK Reticle is fabricated by depositing a high-reflectivity chrome coating onto UV-grade fused silica. Since reticles are often integrated into eyepieces of imaging systems to superimpose a reference pattern onto the observed object, and are most commonly used under transmission conditions, UV-grade fused silica is selected as the substrate.
Unlike resolution test targets made from soda lime glass, UV-grade fused silica offers excellent transmission from the ultraviolet through the infrared spectrum, making it ideal for use in eyepieces as a positional reference.
LBTEK also provides customerization reticle services. For specific pattern or size requirements, please contact LBTEK Technical Support.
Attributes

Reticle
- Optical element diameter: 25.4 mm
- Thickness: 1.5 mm
- Coating: High-reflectivity chromium film
LBTEK RCR1A positive and negative plates extend to the edge of the reticle using a cross method, with a line width of 25 µm. The RCR1B positive and negative plates include one cross and 10 concentric rings marked with numbers, with a line width of 10 µm, and each ring differs in diameter by 1 mm. LBTEK reticles use a 1.5 mm thick UV-grade fused silica substrate, with a transmittance greater than 90% in the 200-1200 nm spectral range. One side is coated with a high-reflectivity chromium film, and the coated area achieves a reflectance of 40% within the visible light range.
The reticle is used to display in the mounting component.
