Deepsee Clear 4" Orange Filter Lens
A press-fit orange lens that turns your DeepSee viewer into a fluorescence filter. The Flipper DeepSee Clear 4 in Orange Filter Lens is a replacement or add-on accessory that snaps onto the front of a Flipper DeepSee Clear 4 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.
- Press-fit onto the DeepSee Clear 4 in viewer – no tools, snaps on and off in seconds so you can swap between clear and orange viewing.
- Clear acrylic body with an orange-tinted lens – matches the optical quality of the viewer it's designed for.
- 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 Clear 4 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 Clear 4 in viewer who want to check coral fluorescence, or photograph it, without swapping to a camera filter.
Not suitable for: the 5 in DeepSee Clear Max viewer – this lens is sized for the 4 in viewer only and won't fit the larger unit. It's a filter accessory, not a standalone viewer or a cleaning magnet.
Goes well with
- Flipper DeepSee Clear Max Viewer (5 in) – the larger viewer in the same 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 5 inch DeepSee Clear Max viewer?
No. This is the 4 in size and is made to press-fit onto the 4 in DeepSee Clear viewer specifically. A separate orange lens is sold for the 5 in Max viewer.
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 Clear 4 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 snap on and off so you can switch between clear and orange viewing without tools.
