08/09seoul precision opticsInfrared Long WavePass FilterInfrared BandPass FilterInfrared Narrow Band Pass Filters are designed for the detection and measurement ofatmospheric gases. Many gases show a specific absorption line in the mid to far infraredrange. With a filter which allows the monitoring of this specific gas absorption, the measurement of gas concentration is possible.Infrared Long Wave Pass filters are designed to transmit wavelength longer than theirspecified 5% cut-on wavelength and to block shorter wavelength than their specified 5%cut on wavelength. Infrared Long Wave Pass Filter and Infrared Wide Band Pass Filters arecommonly used for Motion and Intrusion sensor. The filters are designed with the specification of less than 0.1% in average and Less than 1% in absolute for blocking in order tominimize noise. The filters can come in different sizes based on customer’s requirements.ApplicationInfrared absorption (NDIR) gas sensing, Environment management systemApplicationIndustrial temperature measurement, Continuous temperature control for manufacturing, Security system, Radiation monitor.PropertyTechnology is based on infrared (IR) absorption of radiation called the NDIR(Non – Dispersive Infrared) technique. By detecting the amount of light absorbed, within just a narrow band width that coincides with the resonance wavelength of the specie selected, onegets a measure of the number of molecules, free from interference of other species.PropertyMost of Blocking at range under 5um wavelength in order to reduce the noise, High transmittance at range 7.5 14um wavelength in order to make higher sensitivity of the sensor.BPF GeneralInformationLWP GeneralInformationOrderingInformationItemIR LWP-3.5Cut on(um)TransmittanceBlockingItemCWL(λ0)HBW(λ1 λ2)T(peak)BlockingRange(um)Gas F - 1.940 - 501.940 30nm50 20nm73%1.50 10.00H2O3.54 6.0 80 3.0 0.1NBPF - 2.700 - 602.70 30nm60 100nm73%1.50 4.00H2OIR LWP-5.057.5-13.0 75 4.0 0.1NBPF - 2.82-1802.82 1.0%180 20nm70%1.50 10.0IR LWP-5.55.57.5 - 13.0 75 4.5 0.1NBPF - 3.090 - 1603.09 30nm160 20nm73%1.50 10.00HCIR LWP-6.66.67.5-13.0 75 6.0 0.1NBPF - 3.300 - 1603.300 30nm160 20nm73%1.50 10.00CH4IR LWP-7.77.78.0-13.0 75 6.5 0.1NBPF - 3.295 - 1603.295 30nm160 20nm73%1.50 10.00HC 0.1NBPF - 3.330 - 1603.33 30nm160 20nm73%1.50 10.00HC / CH4NBPF - 3.310 - 1603.310 30nm160 20nm73%1.50 10.00HCNBPF -3.375 - 1903.375 30nm190 20nm73%1.50 10.00HCNBPF - 3.387 - 1903.387 30nm190 20nm73%1.50 10.00HCNBPF - 3.400 - 1203.400 30nm120 20nm73%1.50 10.00HCNBPF - 3.435 - 1603.435 30nm160 20nm73%1.50 10.00HCNBPF - 3.460 - 1633.460 30nm163 20nm73%1.50 10.00HC / CH4IR LWP-8.089.0-13.0 75 7.0NBPF -3.950 - 903.950 30nm90 20nm73%1.50 10.00ReferenceNBPF - 4.260 - 904.260 30nm90 20nm73%1.50 10.00CO2(narrow)NBPF - 4.260 - 1804.26 30nm180 20nm73%1.50 10.00CO2(standard)NBPF - 4.300 - 6004.30 30nm600 30nm73%1.50 10.00Flame

Infrared DLCCoated WindowsThe DLC Coated window is a technique for forming plasma in a high vacuum state andcoating the surface of the product with carbon which is the main component of diamond,and is manufactured using PVD or CVD equipment. DLC coating serves as a window forincreasing the transmittance of the infrared region, and it is applied to products whichrequire high durability and hardness on the surface exposed to the outside. By using adielectric on the DLC coated side, it can show higher transmittance and continues to be ahigh quality productDLC General InformationDCL(Diamond Like Carbon)ThinFilmMetalizationProperty- Type : Window, Lens- Substrate : Silicon, Germanium, ZnS- Hardness : 1500 2000Hv (20Gpa)- Standard : ISO 14577SubstrateOptical CoatingDLC Material PropertyApplication- Night vision , automobile , Home appliances, Mobile Phone- Day and night observation device- Products that are strong against external environments and require high 3.511.8 3.62.26Hardness(kgf/mm2)10,0002,000 8,0005000.050.03 0.20.12.421.8 2.62.15 1.8UV IRVIS IROpaque 10161010 10130.2 0.4Coefficient ofFrictionRefractive IndexLightTransparencyResistance(W cm)Ordering InformationItemSubstrateDLC 3.0SiliconDLC 8.0GermaniumZnSTransmittanceRange(um)Averge(%)3.0 14.0 738.0 14.0 90Durability TEST MethodAdhesion : MIL-C-48497A 4.5.3.1 / Tape TESTHumidity : MIL-C-48797A 4.5.3.2 / 24hrs. 49 , 95 100%, relative humidityAbrasion : TS 1888 / 10,000 wipes with windscreen wiper in water/sand slurrySalt Spray : MIL-C-675C 4.5.9 / 24hrs, salt spray fog exposureSalt Solution : MIL-C-48497A 4.5.5.2 / 24hrs, immersion in salt water033-1 .Wafer LevelPatterning Filter3-2 .IR Metalized Window
