Calcium Fluoride (CaF2) VUV and IR
grade.
Calcium Fluoride (VUV grade) has transmission
range 0.19µm
to 7.2µm.
The refractive index varies from about 1.35 to 1.51 through this range. IR
grade Calcium Fluoride is transparent up to 12µm.
Degradation due to moisture in the atmosphere is minimal, and polished surfaces
may be expected to withstand several years exposure to normal atmospheric
conditions. Due to its low refractive index, Calcium Fluoride can be used
without an anti - reflective coating. Low solubility and wide transmission makes
this material useful for many applications, including mirror substrates for UV
laser systems, windows, lenses and prisms for UV and IR applications.
The maximum temperature CaF2 can
tolerate it is 8000 C in
dry atmosphere. Irradiation of Calcium Fluoride causes some loss in UV
transmission. The material is sensitive to thermal shock.

Axicon Lens
Axicon lens also known as conical lens or rotationally symmetric prism is
widely used in different scientific research and application. Axicon can be
used to convert a parallel laser beam into a ring, to create a non
diffractive Bessel beam or to focus a parallel beam into long focus depth.
Del Mar Photonics supplies axicons with cone angles range from 130° to
179.5° for use with virtually any laser radiation. We manufacture and supply
axicons made from BK7 glass, fused silica and other materials.

Rutile (TiO2) coupling
prisms
Del Mar Photonics offers optical elements made of high quality synthetically
grown Rutile Titanium Dioxide crystals. Rutile’s strong birefringency, wide
transmission range and good mechanical properties make it suitable for
fabrication of polarizing cubes, prisms and optical isolators. Boules having
high optical transmission and homogeneity are grown by proprietary method.
Typical boules have 10 - 15 mm in dia. and up to 25 mm length. Optical
elements sizes - from 2 x 2 x 1 mm to 12.7 x 12.7 x 12.7 mm. Laser grade

Manufacturing challenging optical components
Our group works to characterize the interaction of biomolecules with solid
surfaces, writes Dennis Hore of
University of Victoria, Canada. Nature designs proteins with well-defined
structures in solution. The conformation of these molecules may serve a
structural purpose, or a chemical one in the case of enzymes. In order to
further the progress of technologies that immobilize such molecules on
synthetic surfaces (like biosensors employing enzymes), it is important to
have a detailed understanding and control of the interactions of these
molecules with the surface more
For that project Del Mar has been able to manufacture all shapes of prisms
from CaF2, fused silica, and ZnSe according to our custom specifications.

and other items.
