Quality Longpass Filters MEFH10-400LP

Quality Longpass Filters — Model MEFH10-400LP

Ø25.4 mm, substrate UV Fused Silica.

Product Description

• Passband transmittance > 85%
• Optical Density in Rejection Region (avg) > 5
• Longpass, shortpass optional

LBTEK offers Quality Edgepass Filters that utilize UV-grade fused silica as the substrate. One side of the filter is coated with a filter coating, while the other side features an AR coating. Light comes in the direction of the arrow, allowing specific wavelengths to pass through while rejecting others. These filters are characterized by high transmission rates and high blocking efficiency. LBTEK's Quality Edgepass Filters achieve a transmission rate of >85% within the passband wavelength range and an optical density OD(avg) of >5 in the rejection range. The filters are pre-mounted in black anodized aluminum rings with a diameter of Ø25.4 mm for easy installation and use. In addition to standard edgepass filters, LBTEK provides customized filter solutions to meet specific requirements. For special needs, please contact LBTEK Technical Support.

Quality Longpass Filters

• Longpass Filter
• Passband Transmittance >90%
• Stopand Optical Density >OD 5

LBTEK Quality Longpass Filters transmit light above the cut-on (cut-off) wavelength with a transmittance exceeding 90%. They also suppress light below the cut-on (cut-off) wavelength, achieving an average optical density (OD) of 5 (OD), meaning a transmittance of less than 0.001%. These Quality Longpass Filters are pre-mounted in a black anodized aluminum ring with an arrow marking the direction of light for easy installation.
