LPF590 Precision Longpass Edge Filter: Unlock Clarity Beyond 590nm
Engineered for superior performance in demanding applications, the LPF590 Longpass Optical Filter is your essential solution for selectively transmitting long wavelengths while effectively blocking unwanted shorter wavelengths.
Key Specifications & Benefits:
Precise Cut-On Wavelength: Optimized for a sharp transition at 590nm. Light above this wavelength transmits efficiently, while light below is significantly blocked. (Typical Cut-On tolerance: ±5nm or better - specify yours).
Exceptional Transmission: Achieves >90% peak transmission (state your actual value) in the passband (typically 600nm - 1100nm or substrate limit), maximizing signal strength and system sensitivity.
Deep Blocking (OD >4): Provides Optical Density >4 (OD>4) in the rejection region (UV-Visible below ~580nm), effectively minimizing unwanted background noise, glare, and stray light for cleaner results.
Hard, Durable Dielectric Coating: Features a robust multi-layer interference coating deposited directly onto the substrate. This ensures superior environmental stability, scratch resistance, and long-term reliability compared to soft coatings.
High Quality Substrates: Available on premium optical glass (e.g., BK7, B270) or fused silica for UV performance. Standard thicknesses: 1.0mm, 2.0mm, 3.0mm. Custom sizes and thicknesses available.
Steep Cut-On Edge: Engineered for a sharp transition slope, enabling precise spectral separation critical for fluorescence, imaging, and sensing applications.
Ideal Applications:
Fluorescence Microscopy & Imaging: Perfect excitation filter for dyes emitting above 590nm, isolating the emission signal.
Blood Oximetry (SpO2) Sensors: Used in conjunction with LEDs (e.g., 660nm + 880/940nm) to define spectral bands.
Machine Vision & Industrial Inspection: Enhance contrast, isolate specific material signatures, or remove unwanted lighting effects in the visible spectrum.
Environmental Sensing & Spectroscopy: Isolate specific NIR spectral bands for gas or chemical analysis.
Laser Systems: Block pump wavelengths or unwanted harmonics.
Scientific Research: Essential component in setups requiring wavelength separation beyond 590nm.
