Projection Lens

Features of the Module

• High-resolution image projection with sharp focus
• Wide range of focal lengths for flexible projection distances
• High light transmission with anti-reflective coatings
• Low distortion for accurate image reproduction
• Durable construction suitable for various environments

Description of the Module The Projection Lens is an advanced optical module designed to project high-quality images onto a screen or surface, making it ideal for use in projectors, simulators, and other display systems. This lens works by focusing light from a digital or analog source and projecting it through the lens onto a target area, producing a clear and sharp image with minimal distortion.

The lens is typically composed of multiple optical elements, which are arranged to correct aberrations and enhance image clarity. It often includes aspheric elements to reduce spherical aberration and ensure consistent image quality across the entire projection area. The Projection Lens is designed to operate effectively across a wide range of projection distances, making it versatile for different environments and screen sizes.

General Specification, Manufacturing Tolerances, and Limitations

What is the Module Composed of? And What’s the Classification?

• Optical Glass Elements: Includes lenses made from high-quality optical glass, arranged to correct chromatic and spherical aberrations.
• Aspheric Elements: Reduce spherical aberration and improve image quality.
• Aperture Diaphragm: Controls the amount of light passing through the lens, affecting depth of field and image brightness.
• Mechanical Housing: Robust housing that provides structural integrity and alignment for the optical components.
• Mounting Interface: Custom or standard interfaces (e.g., C-mount) for easy integration into projection systems.

Classification

• Standard Projection Lenses: Designed for general-purpose use, with a balanced projection ratio and focal length.
• Short-Throw Projection Lenses: For projecting large images from a short distance, ideal for small spaces.
• Long-Throw Projection Lenses: For projecting images over long distances, suitable for large venues.
• Ultra-Short-Throw Lenses: Designed for extreme close-range projection, often used in interactive displays.

What’s the Key Components?

• Lens Elements: Multi-element design to correct various optical aberrations and ensure high image quality.
• Aperture System: Provides control over the amount of light passing through the lens.
• Coatings: Anti-reflective, UV, and infrared coatings to optimize light transmission and protect the lens.
• Housing and Mounting Interface: Ensures durability and easy integration into different projection systems.

What’s the Critical Specs?

• Focal Length: Determines the projection distance and image size.
• Aperture Range: Affects light transmission and depth of field.
• Projection Ratio: Defines the relationship between the distance to the screen and the image size.
• Distortion Levels: Ensures accurate reproduction of the projected image without visible warping.

How to Evaluate the Performance? Performance evaluation includes:

• Image Sharpness Test: Assessing the clarity of the projected image at various distances.
• Distortion Measurement: Ensuring straight lines in the image remain straight when projected.
• Light Transmission Efficiency: Measuring the percentage of light that passes through the lens to the screen.
• Color Reproduction Accuracy: Testing the lens’s ability to project accurate colors without chromatic aberrations.

How to Select the Module Selecting a Projection Lens involves:

• Projection Environment: Consider the size of the venue and the distance to the screen.
• Image Quality Requirements: Choose based on the resolution and clarity needed for your application.
• Compatibility with Projector: Ensure the lens is compatible with your projector model and its optical system.
• Special Features: Consider additional features like zoom capability, focus adjustability, and lens shift.

What’s the Application?

• Home Theater Systems
• Commercial Cinema Projectors
• Virtual Reality Systems
• Simulators
• Education and Training Projectors
