Product catalog summary
Overview: This document details the specifications and applications of biconvex lenses manufactured by Khatod, highlighting their use in optical applications such as collimating, diffusing, and focusing light.
Specifications: Various models of biconvex lenses are described, each with specific dimensions and material properties. Key parameters include diameter (D), edge thickness (t), center thickness (S), and effective focal length (EFFL). Materials used are PC, SAN, PMMA, and their infrared variants, each with unique refractive indices and transmission factors.
Geometric Tolerances: Tolerances for lens dimensions and optical properties are specified, including thickness (±0.05%), radius (±3%), and focal lengths (±5%).
Material Properties: The document outlines the physical properties of the materials, such as tensile modulus, yield stress, and glass transition temperature, which influence lens performance under various environmental conditions.
Applications: The lenses are applicable in optical sensors, lighting systems, imaging systems, and signaling, with specific uses in IR security systems, optical encoders, and telecommunication systems.
Custom Applications: Guidelines are provided for interfacing lenses with light sources and detectors, stressing the importance of aligning lens properties with application needs.
Contact Information: Contact details for Khatod's customer service are provided for further inquiries or custom applications.

Optical Engineering Service Biconvex Lenses KE030 - KE035 - KE040 Custom Optical Solutions Development Plastic Moulded Lenses Besides requiring an high level of competence on materials and on the production process, the development of an optical system involves an accurate engineering based on a deep knowledge of optics: this is also true for quite simple systems, such as a single lens, to allow the most efficient, compact and cheap solution to be chosen. In addition, this approach guarantees that the correct solution to a specific problem will be given in the shortest time and with no technological...
