Optical Filters for Medical Devices

Z-Optics is proud to advance the field of medical technology with an expertly engineered range of optical filters. Our filters are developed to meet the precise requirements of medical imaging, diagnostics, and therapeutic devices, providing best-in-class performance and reliability.

Precision Filtering for Medical Excellence

By leveraging advanced coating techniques and high-purity substrates, Z-Optics filters deliver superior contrast, enhanced resolution, and excellent spectral selectivity—key factors for successful medical outcomes. Medical devices from fluorescence microscopes to surgical guidance systems rely on our filters for critical wavelength targeting and exceptional clarity.

Our Medical-Grade Filter Portfolio

Bandpass Filters: Available in FWHM ranges from 12 nm up to 60 nm, with common center wavelengths including 532 nm, 785 nm, 1064 nm, and more. Transmission reaches up to 90%, with high blocking across UV, visible, and NIR regions, making them ideal for fluorescence imaging, OCT, and laser-based diagnostics.
Shortpass & Longpass Filters: Designed for efficient wavelength separation, supporting cut-off points between 395 nm and 1200 nm for sharp spectral discrimination in endoscopic or laparoscopic imaging.
Dichroic Filters: High-reflectivity and precise transition ranges, perfect for multi-channel fluorescence microscopes and surgical applications. Reflect specific bands (e.g., 350–425 nm) and transmit others (e.g., 455–900 nm).
Notch Filters: Block narrow wavelength bands (e.g., 532 nm, 615 nm) while transmitting all others for Raman spectroscopy and laser safety in surgery or diagnostics.
Neutral Density Filters: Provide uniform reduction of light intensity with options ranging from OD 0.1 to OD 5.0, ensuring safe operation for sensitive sensors and laser-based tools.

Key Features and Benefits

Custom and standard sizes (12.7 mm, 25.4 mm, more) for seamless integration into medical instruments.
Outstanding transmission (up to 90%) and optical density performance for precise control over light in clinical environments.
Durable dielectric coatings for long-term stability, sterilization compatibility, and minimal spectral drift.
Ready for demanding uses such as fluorescence microscopy, OCT, laser therapy, endoscopy, and real-time imaging.
