NIR Microscopy: Applications and Design Challenges in the 780–2500nm Range

Five OnlineFebruary 19, 2026Technical ArticleComments are off for this post

Near-infrared (NIR) microscopy objectives (780–2500nm) are essential for “seeing through” opaque barriers.
By balancing high resolution with superior penetration, they enable deep-tissue biological imaging, subsurface semiconductor defect detection, and non-destructive material analysis.
Despite design challenges like specialized material selection (ZnS/Germanium) and complex aberration correction, modern NIR optics provide high-transmittance solutions (≥ 85%) that surpass the physical limits of visible light, driving innovation in both high-tech manufacturing and life sciences.

Five OnlineJanuary 14, 2026Application NoteComments are off for this post

Key Takeaways The Precision Telecompressor optimizes optical systems by intelligently mapping full-frame lens performance onto smaller industrial sensors. By compressing the image field, it restores the native field of view and concentrates luminous flux, providing a one-stop aperture gain and improved Signal-to-Noise Ratio (SNR). This engineering solution enhances MTF (resolution density) and compensates for sensor-lens […]
