Optical Drilling Windows for Medical Imaging

Optical Drilling Windows for Medical Imaging

Precision‑drilled optical windows are optical components with custom‑machined apertures.

They deliver precise control over aperture position, diameter and depth to satisfy diverse optical‑system requirements.

They are widely deployed within spectral‑analysis instruments and optical‑sensor assemblies.

Basic structure:

1. A through‑aperture is precision‑machined either at the center or at an offset position of a polished optical‑glass substrate (e.g. quartz, optical glass).

2. Apertures are typically circular; square or other custom profiles are available upon request.

Functions:

These windows implement segmented optical‑path performance across different zones:

1.Aperture zone: enables unobstructed beam transmission for the main optical path.

2.Non‑aperture zone: retains the window’s native transmission or reflection properties for reflected reference beams and auxiliary optical paths.

Key Custom‑Design Parameters:

1. Aperture size: defined based on beam‑spot dimensions and clearance requirements; aperture shall exceed beam diameter to prevent vignetting.

2. Aperture position: central or eccentric layout, configured to match system optical‑path arrangement.

3. Substrate options: fused silica for UV‑IR, N‑BK7 for visible‑range applications, ZnSe for infrared systems.

4. Surface treatment: anti‑reflection (AR) coatings optional to reduce reflective losses.

Main applications：

(1)Optical sensors.

(2)Laser‑protection assemblies.

(3)Medical‑imaging equipment.

(4)Optical projection systems.
