10nm ± 2nm
> 70% of the common
Mounted in Black Anodized Aluminum Ring
Advantage of Optolong Fluorescence Filter
Multi cavity deposition makes thin film layers to be more than 300.
Durable hard coating film layers.
More than OD5 blocking depth on one single substrate.
Transmission above 90%.
Bandwidth can narrow to 3nm.
Unique design to control rectangularity, overlap.
Wide angle of incidence change.
Suitable for sunlight and other bright light interference work.
The optical signal attenuation rate is small, effectively improve the working distance and light intensity.
Can be directly coating or glue in the infrared transmittance glass by the visible light, rapidly increase the cutoff rate, the vertical incidence in strong light without penetration, light transmission rate is less than 0.2%. And to ensure that working in large angle,and short wavelength shift phenomenon reduction.
More than 20 years’ experience in the production of optical filter,imported coating machine to produce, IAD ion assisted deposition technology and to ensure that the low temperature drift and film firmness stronger.
