Detail Information

High Precision Custom Bandpass Optical Filter With OD4 OD5 OD6 Blocking

 
Felix Glass high precision optical filter OD4 OD5 OD6 filter adopts optical glass or fused silica as substrate, coated with multi-layer interference film to realize single band light transmission, all stray light outside target wavelength can be deeply blocked with OD4, OD5 or OD6 optional grade.
 
OD value represents optical density; higher OD means stronger stray light shielding performance. OD6 ultra-deep blocking can suppress stray light transmittance below 0.0001%, perfectly meet the demand of weak signal detection such as fluorescence. We support fully customized center wavelength, diameter, square size, thickness and edge chamfer, ultra-precision polishing ensures flatness and parallelism for high-end optical equipment.
 

Core Optical Specifications

 
- Optional Blocking Grade: OD4, OD5, OD6
- Target Band Transmittance: ≥85%~92% customizable
- Blocking Transmittance: OD4 ≤0.01%, OD5 ≤0.001%, OD6 ≤0.0001%
- Custom Wavelength: 365nm, 405nm, 532nm, 633nm, 850nm, 940nm etc.
- Surface Quality: 20-10 / 60-40 scratch-dig aerospace & industrial grade
- Shape: Round, square, rectangle, special irregular outline OEM

 

Core Product Advantages

 
1. Three deep blocking grades OD4/OD5/OD6 for selection, ultra-low stray light interference
2. Custom arbitrary center wavelength, match laser, fluorescence, machine vision different working bands
3. High transmittance in passband, reduce light energy loss and improve detection sensitivity
4. High precision polishing, low surface defect, stable coating adhesion, long service life
5. Two substrate options: optical glass and UV-transmittable fused silica
6. Small lab sample order and mass industrial batch supply both acceptable
 

Typical Application Scenarios

 
- Biochemical fluorescence analyzer, nucleic acid detection equipment
- Industrial machine vision positioning, defect detection, barcode reading
- Laser ranging, laser marking, laser safety optical window
- Laboratory Raman, FTIR, spectrophotometer spectral testing
- Medical optical detection, microscopic imaging system
- Infrared sensor, optical measuring instrument
 

OEM Manufacturing Capability

 
We provide full one-stop processing including blank double-sided ultra-precision polishing, multi-layer vacuum bandpass film coating, spectral transmittance testing, edge chamfer and dust-free packaging. Custom wavelength and blocking depth are supported, complete spectral test report will be provided for each batch of filters.
 

Standard FAQ

 
1. What’s the difference between OD4, OD5 and OD6 bandpass filter?
OD value is optical density, higher OD blocks stray light more thoroughly. OD6 is suitable for ultra-precise weak fluorescence detection.
2. Can I customize non-standard center wavelength?
Yes, we can customize bandpass filters for any wavelength from UV to near infrared according to customer drawings.
3. What substrate to choose for UV bandpass filter?
Select JGS1 fused silica substrate, ordinary optical glass cannot transmit deep UV light.
4. What shapes can bandpass filters be made into?
Round, square, rectangular and special irregular shapes are all available for OEM customization.
5. Do you supply small quantity samples for R&D testing?
We accept 1 piece small sample order and provide full spectral performance inspection data.
