Features

Lens (For thru-beam type fiber)

Designation

Model No. Description
Expansion lens
(Note 1)
FX-LE1 Increases the sensing range by 5 times or more.
・ Ambient temperature: -60 to +350 ℃ -76 to +662 ℉ (Note 2)
・ Beam dia: ø3.6 mm ø0.142 in
Sensing range (mm in) [Lens on both sides]
Super-expansion
lens
(Note 1)
FX-LE2 Tremendously increases the sensing range with large diameter lenses.
・ Ambient temperature: -60 to +350 ℃ -76 to +662 ℉ (Note 2)
・ Beam dia: ø9.8 mm ø0.386 in
Sensing range (mm in) [Lens on both sides]
Side-view lens FX-SV1 Beam axis is bent by 90°.
・ Ambient temperature: -60 to +300 ℃ -76 to +572 ℉ (Note 4)
・ Beam dia: ø2.8 mm ø0.110 in
Sensing range (mm in) [Lens on both sides]
(Note 1): Be careful sure to use it only after you have adjusted it sufficiently when installing the thru-beam type fiber equipped with the expansion lens, as the beam envelope becomes narrow and alignment is difficult.
(Note 2): Refer to "Fiber page" for the ambient temperature of fibers to be used in combination.
