IR emitters were installed in a three-axis and hemispherical instrument for the PIR test to implement changes in radiation energy by distance of a person/PET. This enabled us to reduce and automate PIR performance measurements. Hello, This is Fresnel Factory Co., Ltd. We introduce the 3 axis-hemispherical instrument for the PIR test. Demand for PIR […]

We introduce case of mold production for injection molding of ultra-small precision optical lens. In order to make injection molding of ultra-small precision optical lens which uses five sides of hexahedron as effective lens surface, we adopt fine mold processing, Surface roughness of 50nm or less, and tunnel gate. Hello, This is Fresnel Factory Co.,

Today I introduce a article about designing of bicycle light. The design is followed a guide line of German regulation StVZO. Authors use inward grooves facing Fresnel lens and reflector. The link is below. http://ojs.imeti.org/index.php/PETI/article/download/189/412 <The illustration of Germany StVZO regulations> Simulation below demonstrates the simulation result of the optimum design. The simulated illuminance distribution

We have developed a lens transmittance improvement for FIR sensor for absolute temperature measurement, and we introduce successful cases which increased about 10%. FIR (Far InfraRed) sensor is a sensor that detects the temperature by measuring the infrared (IR) emitted from an object and is used in infrared cameras. <Lens transmittance improvement for FIR sensor

Dear Sir/Madam Today I introduce POLY material DPP25 and DPE200 for PIR Fresnel Lens. DPP25(PP) is stronger to hot temperature than DPE200(HDPE). Obviously, DPE200 has cheaper price and higher transmittance rate than DPP25. DPP25 has a lower met flow rate than DPE200, so it takes more time to inject Fresnel lenses and therefore the price
