[INQ. NO. 2507E25] Fresnelfactory Korea Inc. entered the domestic Fresnel lens market in 2002, and now possesses skillful design and tooling ability for Fresnel lenses. Incorporated in 2013, the company has been designated as an ‘Excellent Venture Enterprise’ by the Korean government authorities, and has operated its own research and development center.
Under the catchphrase, ‘Fresnel lens No. 1 in the world,’ the company offers five processing methods, namely: hot-press, injection, casting, roll-to-roll and hot-embossing. Customers can choose suitable methods according to their requirements in terms of precision, mass production, fast R&D time, and price.
With 11 patents related to Fresnel lenses and relevant applications, the firm has obtained international certifications like ISO 9001 and 14001. It has constantly accumulated know-how in the fields of virtual reality (VR), augmented reality (AR), integral photonics, concentrating photovoltaics (CPV), LED lights, and daylights.
FD08-1005 Passive Infrared (PIR) Lens Caps
Ideal for detecting far infrared (FIR) with a wavelength of 8~13μm, the firm’s FD08-1005 PIR lens caps are made of Poly FIR200 or Poly FIR25 materials. Featuring superior resistance against ultraviolet (UV), wide field of view and strong transmittance, they are thus suitable for outdoor locations.
NF26-25 Near-Infrared Fresnel Lenses
Used mainly for NIR and time-of-flight (ToF) sensors, NF26-25 NIR Fresnel lenses permit easy control for detecting direction, and detectable distance and angle. They are therefore applicable for various areas. Made of Poly NIR 212 material, they ensure high detection efficiency. Designed to effectively cut off the unnecessary visible rays, they accurately detect NIR signals. In the NIR areas (with an ordinary wavelength of 905nm), they guarantee high transmittance rate (up to 90%).
FL50-86 Common Fresnel Lenses
Made of polymethyl methacrylate (PMMA), the maker’s FL50-86 common Fresnel lenses promise a high visible ray-transmittance ratio and superb UV-cutting function. As a result, they are ideal for the functional use of collimation (within projection or magnifying equipment) and light-concentration (solar collectors). With a concentric circle-type pattern design, they offer optimal performance in various conditions referring to diffraction and acceptance angle.
The manufacturer also specializes in producing customized polymer materials suitable for a broad range of wavelengths and applications. Among its popular materials are Poly FIR200, Poly FIR25, Poly NIR212, Poly NFIR, and Poly Visible types. Notably, the company can supply special-purpose materials for FD08-10005, NF26-25, and FL-50-86 lenses which are employed for special ranges of wavelengths.
