IDAS Filters OIII 6.0nm 2 (73948)

The OIII Filter is a narrowband filter designed specifically for nebula observation. It allows a precise 3nm bandwidth of light centered on the 500nm wavelength, corresponding to OIII emission lines, while effectively blocking all other light. This makes it ideal for capturing detailed images of planetary nebulae and supernova remnants, enhancing contrast and clarity in astrophotography.

The IDAS OIII 6.0nm narrowband filter offers exceptional performance with a 6.0 +/- 0.2nm bandpass and 98% transmission. It is optimized for use with optical systems ranging from F1.65 and higher, and it fully blocks wavelengths up to 1300nm. Each filter undergoes individual inspection and quality measurement, and it comes with a unique product code and its actual measured plot for verification. Manufactured in Japan, this filter ensures precision and reliability.
