F25ND3—FUV-MAMA
Description
The F25ND3 mode with the FUV-MAMA detector provides broad band imaging with an attenuation of 10-3. The R80 and central pixel flux are unmeasured but assumed to be approximately the same as produced by the F25QTZ filter
Recommended Uses
Recommended for broad-band imaging of bright objects requiring 10-3 attenuation to meet FUV-MAMA bright object protection limits.
