If you already own a 37mm (1.46") gobo lens, you’ve probably asked one very important question:

“Is my 37mm lens compatible with your projector?”

The short answer is yes. But the real-world question doesn’t stop there.
As one user recently pointed out, the fixing (mounting) part matters just as much as the lens diameter.

This article gives you the complete, search-engine-friendly answer for gobo lens size 37mm compatibility — including the often-overlooked fixing bracket issue.

✅ The Direct Answer: 37mm Gobo Lenses Are Compatible

Let’s start with the official confirmation from a projector manufacturer:

Q: I already have a lens that is 37mm (1.46") in size. Could you please let me know if it is compatible with your product?
A: Yes. Our projector is compatible with 37mm lenses.

So if your main concern is gobo lens size 37mm, you can move forward — the lens diameter itself is fully supported.

The Real-World Problem: The Fixing (Mounting) Part

Here’s where things get tricky — and where most compatibility guides stop short.

One user followed up with this exact concern (translated from Korean):

“The fixing part I received looks like this. Is it still possible with this?”

Even if your gobo lens size is 37mm, compatibility also depends on:

The shape and design of the fixing/mounting ring

Whether the bracket matches your projector’s lens holder

If the fixing part allows the 37mm lens to sit securely

How to Check If Your 37mm Gobo Lens Will Actually Fit

Before you assume compatibility, do this quick 3-step check:

1. Measure the lens outer diameter

Make sure it’s exactly 37mm (1.46 inches).
Even 0.5mm off can cause loose fit or no fit.

2. Inspect the fixing (mounting) part

Does it screw in?

Does it use a spring clamp?

Is it a custom shape from an old projector?

3. Compare with your projector’s lens holder

If the fixing part shape doesn’t match the holder, the lens won’t stay in place — even if the size is correct.

🛠 What to Do If the Fixing Part Doesn’t Match

If your 37mm gobo lens has an unusual fixing bracket, you have several options:

Pro tip: When asking a seller “is my 37mm lens compatible?” — always include a photo of your fixing part, not just the lens.

Gobo lens size 37mm is compatible with standard projectors.
But don’t stop at diameter — check your fixing part.

The user who asked about the oddly shaped mounting bracket asked the right follow-up question.
Make sure you do the same before buying or installing.
