Why Choose Custom Optical Filters?
Custom optical filters are game-changers for precision optics, offering tailored performance that off-the-shelf options can’t match. Here’s why they stand out:
- Streamlined Design: In laser systems, custom filters reduce the number of components, cutting complexity and costs.
- Superior Signal Quality: Optimized signal-to-noise ratios boost efficiency, critical for high-resolution imaging in microscopy or spectroscopy.
- Perfect Fit: Tailored wavelengths, sizes, and coatings ensure seamless integration into your unique setup.
Types of Customizable Filters
OPTOStokes offers a wide range of custom optical filters, each designed to meet specific application needs. The table below outlines key types and their customizable parameters:
| Filter Type | Function | Applications | Custom Parameters |
|---|---|---|---|
| Bandpass Filters | Pass specific wavelength range, block others | Fluorescence microscopy, astronomy | Center wavelength, bandwidth, coatings, OD5+ |
| Long-Pass Filters | Pass wavelengths above cutoff, block shorter ones | NIR spectroscopy, UV blocking | Cutoff wavelength, slope, substrate material |
| Short-Pass Filters | Pass wavelengths below cutoff, block longer ones | UV imaging, laser systems | Cutoff wavelength, OD5+, transmission rate |
| Neutral Density (ND) | Reduce light intensity evenly | Photography, laser power control | Optical density (e.g., 0.3ND), size, material |
| UV/IR Cut Filters | Block UV/IR, pass visible light | Machine vision, photography | UV/IR cutoff, transmission range, thickness |
| Polarization Filters | Transmit specific polarization direction | Glare reduction, display enhancement | Polarization type, axis, transmission rate |
| Dual/Multi-Band Filters | Pass multiple wavelength bands | Multi-spectral imaging, flow cytometry | Band count, wavelength ranges, isolation |
| Laser Filters | Pass specific laser wavelengths | LIDAR, laser communication | Center wavelength, damage threshold, size |
| Interference Filters | Select wavelengths via thin-film interference | Spectroscopy, remote sensing | Bandwidth, coating layers, substrate flatness |
Bandpass Filters
Perfect for isolating specific wavelengths, like 520 nm for GFP imaging. Customize center wavelength, bandwidth (e.g., 20 nm), and coatings (e.g., TiO₂/SiO₂) for high transmission (>90%) and deep blocking (OD6+).
Long-Pass and Short-Pass Filters
Long-pass filters, ideal for NIR spectroscopy, can be tuned to cutoffs like 600 nm. Short-pass filters, used in UV imaging, support cutoffs like 450 nm with high OD for IR blocking. Both offer custom substrates and slopes.
Specialty Filters
Neutral density filters control light intensity for laser experiments, while UV/IR cut filters enhance color accuracy in photography. Polarization filters reduce glare in displays, and multi-band filters enable simultaneous detection in flow cytometry.
Laser and Interference Filters
Laser filters match wavelengths like 532 nm for LIDAR, with high damage thresholds. Interference filters, used in Raman spectroscopy, allow precise bandwidth control with custom coating layers.
