Fresnel effect

With the Source Four Fresnel, you choose the lamp wattage that best suits your particular application and energy requirements - from 375W to 575W to 750W lamps. And when you need to relamp a Source Four Fresnel, ETC's smart new design makes your work easier than ever. Our innovative socket and access door let you change out the lamp from underneath the fixture -- without having to break focus -- saving on work, time and trouble.

Your lighting rig is now complete. ETC's new Source Four Fresnel brings you the soft-focus lighting and sparkle you love, with Source Four quality and efficiency. Lighting designers have long applied the romance of Fresnel light -- the controlled blending washlight and soft beam you can only get from a barn-doored Fresnel. Now you have that singular light quality and effect, and more, in a Source Four fixture.

Our basic tube lens modules come with an Achromat tube lens size of your choice. A male RING mount is part of tube so the C60-RING is not required. Sizes of Achromat tube lenses available:

We've combined the best of our acclaimed Source Four HPL lamp technology with the unique optics of a traditional Fresnel. (And that means you can further streamline your fixture lamp inventory with a single source - the HPL.) ETC's Fresnel gives you the high-performance light output and energy savings of a Source Four and the lighting characteristics that only a Fresnel optical system can provide. We've combined that classic system with a special ETC dichroic reflector design, enabling the HPL 750W Source Four Fresnel to equal the light output of 1000W Fresnel fixtures.

Below you can find tube lenses, extension tubes and focus side components for the MIM System. Please contact us or fill out the form at the bottom of this page if you have any questions regarding our tube lenses. You can find more information regarding MIM setups and components on our main MIM Page.

Collimated space tube with provision to move a 25 mm diameter lens element with 25 mm travel. Used for TIRF systems to focus the laser to objective BFP.  Specify F.L. of 25 mm Acrhomat lens.

Assembly places for FC fiber optics connector tip at the image plane of a C60-TUBE-XXX lens. Fiber connector may be translated using a micrometer heat adjuster. Used for TIRF system to set the TIRF angle.

Replace your old Fresnels with a fixture that's built to last: like all the Source Fours in your rig, the ETC Fresnel is made of ETC-quality die-cast aluminum.

Fresnel lens

Non-rotating length adjustment with 8 mm travel and 30 mm aperture. Female RING mounts on both sides. 41 mm length +/- 4 mm. It can be combined with C60-RING-30 mm and C60-RING-C-MALE to make an adjustable C-mount adapter with 8 mm of travel, which is useful for bringing multiple cameras into co-focus. .

It's a zoom to focus. With the Source Four Fresnel, you get that timeless Fresnel light in a 21st-century fixture. ETC's innovative mechanical design has simplified the focusing for you. Whatever physically awkward spot you're working in, we make it easier for you to adjust the fixture from spot to flood, with a full-sized zoom knob you can get a real grip on. We've also engineered the fixture-housing to eliminate light leaks and minimize spillage.
