Frequently Asked Questions (FAQ)
What is the wavelength range of these ND filters?
These Neutral Density (ND) filters cover a broad wavelength range of 400nm to 1100nm, making them suitable for applications spanning visible light and near-infrared spectrums.
What does the "OD at 550nm" value mean?
OD stands for Optical Density. It measures the light attenuation of the filter at a reference wavelength of 550nm. Higher OD values indicate lower transmission (e.g., OD 1 transmits 10% of light, while OD 2 transmits 1%).
Can I order custom optical densities or custom sizes?
Yes. While the list shows our standard stock items, we can customize optical densities, shapes, dimensions, and coatings to meet your specific project requirements. Please contact us for custom inquiries.
Are the spectrograms provided representative of actual performance?
Yes, the spectrograms illustrate the transmission and attenuation characteristics across the 400-1100nm range, verifying flat and consistent attenuation performance.
How should I handle and clean these optical density filters?
Always handle the filters by their edges using powder-free gloves or finger cots. Clean them using optical-grade lens tissues and high-purity isopropyl alcohol or specialized lens cleaning solutions to prevent surface scratching.
