A cemented lens is also called an achromatic lens. The manufacturing process glues two or more lens elements of different materials together. The performance of imaging in multi-color (white light) is much higher than that of single lens. Correcting the dispersion of the glass, eliminating the problem of chromatic aberration, achromatic lenses have been widely used in multi-color illumination and imaging, improving cost-effectiveness.
Basic technical parameters:
Dimensional tolerance ± 0.05mm
Surface accuracy 1 / 2λ, λ / 4 per φ25.4mm
Eccentricity: ≥1 ′
Smoothness 60-40, 40-20, 20-10, 10-5
Chamfer 0.2-0.3mm × 45 °
Clear aperture:> 90%
Polishing: High-precision double-sided polishing
The optical performance of achromatic double cemented lenses is far superior to single lenses. Achromatic lenses are suitable for various applications such as fluorescence microscopy, image relay, inspection or spectroscopy
