Specs
| Peak Wavelength | 365 nm |
|---|---|
| ZWB2 Filter | No |
| UV Leakage Note | No ZWB2 filter is fitted, so visible violet/blue leakage from the 365 nm die and its phosphor-free package is emitted directly and is clearly visible. For fluorescence work where visible leakage washes out the response - currency and document verification, mineral inspection, forensics - an aftermarket ZWB2 filter is effectively required. GC's listing does not mention this, while it does advertise exactly those use cases. |
