Products Description
BP620 Bandpass Filter | FWHM 100nm, 620nm Center Wavelength
The OPTOStokes BP620-100nm is a high-performance broadband bandpass filter designed for optical systems that require high light throughput and precise spectral isolation. Featuring a wide peak transmission band exceeding 90% from 580nm to 660nm, this optical filter ensures maximum signal capturing efficiency. It delivers a robust out-of-band rejection with Optical Density greater than 5 (OD > 5) in the short-wavelength UV-Vis region (350–550nm) and OD > 3 in the near-infrared region (705–1100nm), ensuring exceptional image contrast and reliability.

Applications in Agriculture and Food Inspection
With its wide 100nm passband spanning the orange-red spectrum, the BP620-100nm filter is highly optimized for automated machine vision. In advanced agricultural sorting, it isolates the key reflectance wavelengths necessary for assessing fruit maturity and leaf chlorophyll concentration. Furthermore, for non-destructive food inspection, this premium bandpass filter accurately separates visible fluorescence emission wavelengths from background illumination, facilitating the rapid detection of surface blemishes and foreign contaminants on high-speed conveyor lines.
Customization and OEM Solutions
OPTOStokes combines world-class quality with extensive custom manufacturing capabilities to seamlessly fit your instrument design. We support rapid machining into circular, square, or specialized geometric configurations tailored to your custom optomechanical layouts. Filters can also be supplied pre-mounted in standardized black anodized aluminum threaded mount rings. By maintaining an extensive in-stock selection of raw optical materials, we secure predictable supply chains and fast delivery schedules for both prototyping and mass production.
Eliminate Stray Light and Procurement Delays
Optical engineers and procurement managers often encounter challenges with spectral drift and delayed component deliveries that stall product development. Inadequate out-of-band blocking leads to sensor saturation and inaccurate data collection. OPTOStokes eliminates these risks by utilizing resilient thin-film hard coatings that maintain long-term environmental stability. Whether you are validating a new design or scaling up an existing platform, our technical support team delivers reliable lead times and guaranteed quality.
