Product Overview

LSR Transparent Optical VR Silicone Lens is a high-precision liquid silicone rubber optical component custom-developed for virtual reality (VR) display systems. Designed to meet the stringent requirements of modern VR devices for light transmission, optical uniformity, and long-term comfort, this product leverages the inherent properties of low-viscosity liquid silicone rubber and precision injection molding processes to deliver consistent optical performance that meets consumer and enterprise VR equipment standards.

At 橡楚（湖北）橡胶有限公司, we produce this lens exclusively from medical-grade raw liquid silicone rubber, with no added recycled materials or harmful plasticizers. Unlike traditional polycarbonate (PC) or acrylic VR lenses, our LSR optical lens combines excellent light transmission with soft, flexible mechanical properties, reducing pressure on the user's face during extended VR sessions while maintaining stable optical imaging accuracy. Our in-house molding and post-processing capabilities allow us to produce custom-shaped, multi-curve lenses tailored to different VR headset form factors, supporting both consumer-facing standalone VR devices and professional enterprise training VR systems.

Technical Specifications

Material Properties

Physical Performance

Process Parameters

Our LSR optical lenses are manufactured via precision liquid injection molding (LIM) with controlled in-mold curing:

• Curing Temperature: 130°C-150°C
• Curing Time: 90-180 seconds (adjusted for lens thickness)
• Dimensional Tolerance: ±0.01mm (for standard thickness <5mm)
• Maximum Lens Diameter: 80mm (custom larger sizes available upon request)
• Post-processing: Precision optical polishing, plasma cleaning, anti-fog coating optional

Product Advantages

1. Superior Optical Consistency

Unlike thermoplastic optical lenses that are prone to residual stress and uneven refractive index after injection molding, addition-cured LSR forms a uniform molecular network during curing, resulting in consistent refractive index across the entire lens surface. This reduces imaging distortion and chromatic aberration, delivering a clearer, more stable viewing experience for end users.

2. Enhanced Wear Comfort

LSR is inherently soft and low-modulus compared to rigid PC and acrylic materials. Our LSR VR lenses can be integrated directly into the facial interface of a VR headset, eliminating the need for separate soft foam padding in direct contact with the user's skin. The material's natural non-slip properties and conformability reduce pressure points around the eyes and nose, making extended VR use more comfortable for all face shapes.

3. Excellent Biocompatibility and Hygiene

Our raw LSR materials meet biocompatibility requirements for skin contact, are non-irritating to human skin, and do not leach harmful additives even during long-term use. The non-porous surface of LSR resists oil and sweat absorption, making it easy to clean and disinfect between uses — a critical advantage for shared VR devices in arcades, training centers, and public exhibitions.

4. Stable Performance Across Environmental Conditions

LSR maintains its mechanical and optical properties across a wide temperature and humidity range, unlike thermoplastics that can warp at high temperatures or become brittle at low temperatures. This makes our LSR VR lenses suitable for use in both consumer devices operated in indoor home environments and rugged enterprise VR systems used in industrial or outdoor training scenarios.

5. Design Flexibility for Custom Forms

Liquid silicone rubber's excellent flowability during molding allows us to produce complex aspheric and free-form lens shapes that are difficult to achieve with conventional rigid materials. We can accommodate custom curvature, thickness, and edge contour requirements to match the specific optical design of any VR headset.

Applications

Our LSR Transparent Optical VR Silicone Lenses are designed for a wide range of virtual reality and related applications:

1. Consumer Standalone VR Headsets: Used as primary optical lenses or integrated soft interface lenses for mainstream consumer VR devices, balancing imaging quality and daily use comfort.
2. Enterprise Professional VR Training Systems: For shared VR training equipment in industries such as manufacturing, healthcare, and education, the easy-to-clean biocompatible surface meets repeated multi-user hygiene requirements.
3. VR Arcade and Location-Based Entertainment: Durable, impact-resistant LSR lenses withstand frequent use and accidental bumps, reducing maintenance and replacement costs for commercial VR operators.
4. Augmented Reality (AR) Waveguide Cover Lenses: The high transmittance and low haze properties of our LSR make it suitable for protective cover lenses for AR waveguide modules, providing impact resistance without compromising display clarity.
5. Medical VR Training and Rehabilitation Devices: The biocompatible skin-safe material meets regulatory requirements for medical device accessories, suitable for long-term use in patient rehabilitation and clinical training scenarios.

Selection Guide

Hardness Selection

We recommend different Shore A hardness ranges based on your product design:

• 20-30 Shore A: For lenses integrated directly into the facial interface, prioritizing maximum conformability and comfort.
• 30-40 Shore A: General-purpose option for most consumer VR headsets, balancing softness and structural stability.
• 40-50 Shore A: For standalone primary optical lenses that require higher structural rigidity to maintain precise curvature.

Size Specifications

Our standard product range supports diameters from 30mm to 80mm, with thickness from 2mm to 10mm. We can accommodate custom dimensional and curvature requirements based on your optical design drawings; please share your technical drawings for a customized quote.

Material Grade

We offer two standard material grades to match different application needs:

• General Grade: For consumer VR devices and commercial entertainment applications, meeting all standard optical and mechanical requirements.
• Medical Grade: For medical VR rehabilitation and training devices, with additional biocompatibility testing to confirm compliance with skin contact requirements.

Quality Assurance

At 橡楚（湖北）橡胶有限公司, we operate our manufacturing facility under a quality management system certified to ISO 9001, with strict quality control protocols implemented at every stage of production:

1. Raw material inspection: Every batch of incoming liquid silicone rubber is tested for light transmittance, hardness, and impurity content to ensure compliance with our specifications.
2. In-process quality checks: Dimensional accuracy and surface quality are inspected after molding and polishing to eliminate defective products before final testing.
3. Final optical testing: Every batch of finished lenses undergoes transmittance, haze, and imaging distortion testing to confirm performance meets technical requirements.
