E-Tay’s Fresnel Lens in Daily Life and Capability
Frensnel lens for LED light distribution Fresnel lens can be moulded or injection mold depending on light source model, COB light source (value of luminous), light angle, distance from lamp bead to lens d lens size, thickness, material. Application: Good for night vision, stage lights, high bay lights, flood lights, wall wash lights, traffic lights, film and television lighting, etc. Extended application: Use sandblasting, compound eyes, atomization, anti-glare, diffuser and other methods to make the light spot more uniform and soft...
LED LIGHT DISTRIBUTION FRESNEL LENS (YOU CAN CHOOSE MOLDED OR INJECTION)
Frensnel lens for LED light distribution Fresnel lens can be moulded or injection mold depending on light source model, COB light source (value of luminous), light angle, distance from lamp bead to lens d lens size, thickness, material. Application: Good for night vision, stage lights, high bay lights, flood lights, wall wash lights, traffic lights, film and television lighting, etc. Extended application: Use sandblasting, compound eyes, atomization, anti-glare, diffuser and other methods to make the light spot more uniform and soft.
INFRARED SENSOR LENSES PIR FRESNEL LENSES
Are used on Ceiling 2.7-3 meters and above 3 meters, on wall-mounted 1.2-1.5m switch type, on wall-mounted 2m-2.5m, security typed 0.8 meters desktop type, and under 0.5 meters foot type e Infrared thermometer and proximity sensor. To design and make a PIR Fresnel lens infrared sensor lens, out technician needs information of Probe model specifications, Product drawings, 3D or 2D diagram of the probe placement relative to the lens, required sensing angle and sensing distance (horizontal and vertical), indoor application OR outdoor application, color requirements, and Is there a pet-proof function.
FRESNEL LENS FOR PROJECTOR
The front Fresnel lens and the rear Fresnel lens. The front Fresnel lens is close to the light source and generally centered, requiring approximately parallel light to be emitted. The rear Fresnel lens is generally designed to be off-center, and when it hits the screen, it is generally above the square. The larger the picture, the darker the brightness. Consider the customer's light source. If the four sides of the projected image become yellow after the adjustment is clear, the combined focal length is too short, and it is recommended to use a lens with a longer focal length; the opposite is true if it is blue.
PHOTOVOLTAIC FRESNEL LENS AND SOLAR COLLECTOR LARGE FRESNEL LENS
PMMA Fresnel lens, equal ring design and variable ring equal tooth depth design, the focal length is long, the spot is large, and the focal length is short, the spot is small. The difference between curved tooth and straight tooth processing, the maximum tooth depth of the tooth tip R0.01-0.02mm is recommended not to exceed 1mm, 0.25-0.5 is appropriate. The shallow teeth are for long focal lenses, and the depth of teeth is for short focal lenses.
The maximum 2mm deep thread can be suppressed, and the maximum can be processed diagonally 2 meters or 1*1.6 meters molded lens SOG+ tempered glass, equal ring design and variable ring equal tooth depth design, the focal length is long, the spot is large, and the focal length is short, the spot is small. The difference between curved tooth and straight tooth processing, tooth tip R0.01-0.02mm maximum tooth depth It is recommended not to exceed 1mm, preferably 0.25-0.5, shallow for long focal lenses, and tooth depth for short focal lenses. The maximum diameter of 2m lenses can be pressed. Linear heat collection and polarized light. Long focal length means larger spot, shorter focal length means smaller spot. The maximum tooth depth of tooth tip R0.01-0.02mm is recommended not to exceed 1mm, 0.4-0.5mm is appropriate, shallow tooth is for telephoto lens , Tooth depth is for short-focus lens, PMMA material can make up to 1*1 meter lens, SOG+ tempered glass can make up to 1.4*2 meter.
REFLECTIVE / REAR VIEW FRESNEL LENS
Fresnel Lens can be applied in ATM cash machine series, the largest coating is 500*500 at present, the tooth tip R0.01-0.02mm, generally the dense tooth 0.1-0.3mm The shorter the focal length, the larger the viewing angle.
3D VIRTUAL LENS
Fresnel used in 3D virtual lens provides large field of view, above 60 degrees, combined with convex lens to achieve 90 degrees. The Capacity 10mm thickness PMMA lens, The ring pitch design can be 0.1-0.5mm
MAGNIFIERS AND MOBILE PHONE SCREEN MAGNIFIER
Fresnel lens bookmark magnifier, card magnifiers, and full page magnifiers are our main product.Can made by flexible PVC or rigid acrylic
E-Tay’s mobile phone screen magnifier is 1.5mm thickness PMMA Fresnel lens , tooth tip R0.03. Our screen magnifier are suitable for all kinds of smartphones. The ring pitch design can be 0.3-0.5mm
MOLD PROCESSING CAPABILITY:
Tooth tip R0.01mm, ring distance less than 0.03mm, the maximum processable mold diameter is 2000mm, the minimum processable mold diameter is less than 1mm, the longest focal length can be designed and processed more than 5 meters, the minimum focal length can be designed and processed less than 5mm, and the highest finish is R0.014 microns , Generally R0.02 microns.
COMPRESSION MOLD
Requires additional tooling or special requirements for mirror panels
Customer need to pay for mold fee at first time. Mold fee refund can be negotiated for repeat orders. Customer may takeaway mold, but special design is not included.
