Pulsar Thermion & Thermion 2 Series Flip Open Cap (Diaptor) (Not for Thermion 60 Series)
Want protection for your Thermion Diopter Lens? We got it!
Pulsar Thermion flip open cap for the diopter side. We started with a quality Butler Creek cap and then modified it to fit the Thermion diopter lens it stays on very well and easy to operate and quiet operation. This cap can be mounted sideways by rotating the cap. The cap will then open to the left or right to keep it out of your way when shooting (see pictures above for reference).
IF you do not like or use an eye cup with your Thermion then this is a must have accessory, it helps protect and keep your diopter lens clean and protected.

No. Caps are sized to a specific lens diameter, and a thermal eyepiece is not the same size as a riflescope ocular. This cap is modified to fit the Thermion and Thermion 2 diopter, and it will not fit the Thermion 60 series, which uses a different eyepiece.
It covers the glass when you're not using it. Grit, rain and fingerprints on a diopter lens make the screen look soft, and a scratch is permanent. A flip cap like this one stays attached, so it can't get lost in the leaves, and it swings aside the moment you need to see.
Start with your scope model. Thermion and Thermion 2 owners use this eye side cap, and Thermion 60 owners need the 60 series cap instead. Then decide which way you want it to open. This one rotates on the eyepiece, so you can set it to swing left or right.
