Ohara currently melts more than 130 environmentally safe glass types, free of both lead and arsenic and produces more than 300 tons of high quality optical glass each month available as strip, slab, cut blanks, pressings and other forms.

Properties ofoptical glass

The rear lens focuses and magnifies the beam onto the larger 5.5” front Fresnel lens, maximizing light utilization. Our dual lens optical design makes the Fresnel 2X twice as powerful as the original Aputure Fresnel, and makes the 120d II almost 10 times brighter than with the reflector.

The Fresnel 2x design features dual optical intensifying elements, a large 5.5” front Fresnel lens, improved ventilation, and the elimination of light leaks, making this the ultimate Bowens Mount Fresnel.

Ohara optical glass is used in various advanced optical systems and an array of devices, such as digital cameras, LCD projectors, medical devices, microscopes, astronomical telescopes, and more.

By utilizing a new rotating barrel design, the Fresnel 2X creates an intuitive user experience, similar to a camera lens. The smooth focus throw gives users an ability to accurately finesse the beam angle of their light source, allowing you to easily spot or flood your light with a simple twist.
