Custom Optical Equilateral Dispersive Prism For Medical Imaging Devices
Material
1.High-Grade Optical Glass: Typically fabricated from BK7, fused silica, or specialized medical-grade optical materials to ensure biocompatibility and high light transmission in visible to near-infrared (NIR) spectra.
Key Properties
1.Precision Geometry: Equilateral design (60°-60°-60°) guarantees consistent dispersion angles for accurate wavelength separation.
2.Surface Quality: λ/10 surface flatness minimizes light scattering, critical for high-resolution imaging.
3.Dispersion Efficiency: Optimized refractive index uniformity for sharp spectral resolution in medical diagnostics.
Core Function
1.Spectral Filtering: Separates polychromatic light into discrete wavelengths for hyperspectral or multispectral imaging systems.
2.Beam Alignment: Maintains collimation in endoscopes, OCT (Optical Coherence Tomography), and laser-based surgical devices.
Applications
1.Medical Diagnostics: Used in fluorescence imaging, blood oxygenation monitoring, and tissue spectroscopy.
2.Surgical Tools: Integrated into laser scalpels and endoscopic probes for real-time tissue differentiation.
