Deepsee Orange Filter Lens Nano 3"
A press-fit orange lens that turns your Nano viewer into a fluorescence filter. The Flipper DeepSee Orange Filter Lens Nano 3 in is an accessory lens that attaches to a Flipper DeepSee Nano 3 in viewer. It blocks blue light, which is what makes coral fluorescent pigments look muted or invisible under standard reef lighting, so pigments that glow green, pink or yellow under blue light show up clearly to your eye rather than only through a camera filter.
Key features
- Blocks blue light - cuts the wavelengths that wash out fluorescent coral colour under actinic and blue-heavy reef lighting.
- Sized for the Nano 3 in viewer - attaches to the Flipper DeepSee Nano viewer specifically, not the larger 4 in or 5 in models.
- Optical-quality lens - matches the clarity of the viewer it's designed for, so the filter doesn't blur the magnified view.
- Suited to photography as well as viewing - a cheaper way to see true fluorescence than shooting through a camera-mounted filter alone.

What's included
One orange filter lens only. The DeepSee Nano 3 in viewer body and its mounting magnet are sold separately - this accessory does not include a viewer.
Suitable for, and not suitable for
Suitable for: owners of the Flipper DeepSee Nano 3 in viewer who want to check coral fluorescence, or photograph it, without swapping to a camera filter.
Not suitable for: the 4 in DeepSee Clear or 5 in DeepSee Clear Max viewers - this lens is sized for the Nano 3 in viewer only and won't fit the larger units. It's a filter accessory, not a standalone viewer or a cleaning magnet.
Goes well with
- Flipper DeepSee Clear Viewer with 4in Lens - the next size up in the DeepSee range, for buyers who haven't settled on a size yet.
Warranty and delivery
Flipper does not publish a separate warranty term for this accessory lens beyond its general product warranty; your rights under the Australian Consumer Law apply regardless. Ships as standard freight.
Common questions
Does this lens fit the 4 inch DeepSee Clear viewer?
No. This is the Nano 3 in size and is made to fit the Nano viewer specifically. A separate orange lens is sold for the 4 in and 5 in DeepSee viewers.
Why would I want an orange lens over the clear one?
Coral fluorescent pigments are excited by blue light but hard to see clearly under it, because the blue light itself washes out the glow to the naked eye. The orange lens filters that blue light out, so the fluorescence reads clearly rather than being drowned out by the tank's own lighting.
Does it come with a viewer?
No. This listing is the filter lens only. You need a Flipper DeepSee Nano 3 in viewer already, or bought alongside it, for the lens to attach to.
Is it a permanent fit?
No - it's a press-fit accessory, designed to attach and remove without tools so you can switch between clear and orange viewing.
