650nm Shortpass Filter
The 650nm shortpass filter is crafted to deliver precise optical performance, making it an ideal choice for systems requiring accurate separation of shorter wavelengths. Its balanced design combines high transmission in the target range with strict blocking of unwanted wavelengths, addressing the core needs of professional applications.
Key Performance
This filter features a sharp 50% transmission cutoff (CWL) at 650nm±5nm, creating a clear boundary between transmitted and blocked wavelengths. It achieves over 90% transmission from 410nm to 640nm, ensuring efficient passage of visible short wavelengths—critical for maintaining strong signal integrity.
Notably, it provides reliable blocking with less than 1% transmission in two key ranges: 350-375nm (to reduce ultraviolet interference) and 700-1000nm (to eliminate near-infrared noise). With a standard thickness of 1.0mm (other thicknesses available in stock) and a 60/40 surface finish, it minimizes light scattering, preserving optical clarity in high-precision setups.
Application Cases
- Machine Vision Systems: In automated inspection lines, it enhances contrast by filtering out 700-1000nm infrared light, ensuring accurate detection of color-coded components or printed labels that rely on visible short wavelengths.
- Fluorescence Microscopy: When paired with fluorophores emitting in 410-640nm, it blocks stray infrared light from excitation sources, sharpening fluorescent signal visibility and reducing background noise.
- Spectral Analysis: For colorimetry or material testing focusing on visible short wavelengths, it eliminates ultraviolet (350-375nm) and infrared (700-1000nm) interference, delivering more precise spectral data.
