What is a Wedge Prism?
A wedge prism is an optical prism with a slight angular difference between its two flat surfaces. It is commonly used to deviate or deflect a laser beam at a small, precise angle. K9 optical glass wedge prisms provide high transparency, low bubble content, and stable performance across the visible spectrum.

FAQ / People Also Ask
Q1: What is the purpose of a wedge prism?
A wedge prism is used to slightly deviate a light beam without dispersing it. It is ideal for aligning laser paths or adjusting optical axes in imaging systems.
Q2: What materials are commonly used for wedge prisms?
K9 glass and fused silica are the most common materials. K9 offers good visible transmission and cost-effectiveness, while fused silica provides higher UV transmission and lower thermal expansion.
Q3: Can wedge prisms be customized?
Yes, VY Optics offers customized wedge angles, dimensions, coatings, and mounting solutions according to customer requirements.
Q4: What is the difference between a wedge prism and a right-angle prism?
A wedge prism has a small angle deviation for beam steering, while a right-angle prism changes the direction of light by 90°. They serve different optical alignment purposes.
How to Choose the Right Wedge Prism
Choosing the right wedge prism depends on wavelength range, material, coating, and wedge angle. A proper combination ensures stable and accurate beam deviation performance.
- Wavelength Range: Match the prism material to your system’s wavelength (e.g., K9 for visible, fused silica for UV).
- Wedge Angle: Determines the degree of beam deviation; precision is crucial for laser alignment.
- Surface Quality & Flatness: Better quality reduces beam distortion.
- Coating Selection: AR coatings enhance transmission and minimize reflections.
- Environmental Conditions: Consider operating temperature and humidity.
- Customization: VY Optics provides OEM options to match any optical setup.
