Description
Technical field
The present invention relates to a kind of ultraviolet passes through visible absorption glass and ultraviolet passes through visible absorption optical filter.
Background technology
Currently, in the ultraviolet lamps such as ultraviolet hardening resin light source, using while visible ray is absorbed
The ultraviolet for passing through with making ultraviolet selecting passes through visible absorption optical filter, used as the black glass for constituting this optical filter
Glass, for example, propose the silicate glass described in patent documentation 1 (Japanese Patent Publication 4-32019 publication).
Patent documentation 1：Japanese Patent Publication 4-32019 publication
The content of the invention
But, the black glass that patent documentation 1 is recorded, in order that UV transparent rate is improved or adjusted to light transmittance
It is whole and contain PbO or As2O3, in contrast, in recent years in order to reduce carrying capacity of environment, seek in addition to not comprising Pb, As, also
Glass not comprising elements such as Cd, Cr.
On the other hand, it is for energy-saving and the high efficiency of operation, saturating as the ultraviolet used in above-mentioned optical filter
Visible absorption glass is crossed, even if being required not comprising above-mentioned element, it may have the absorbability of excellent visible ray and ultraviolet
The permeability of line.
If additionally, overexposure can be referred to as with the big light of high brightness illumination radiation illumination to optical glass
(solarisation) coloring phenomenon, so as to easily cause the reduction of glass transmission rate, particularly in irradiation comprising ultraviolet
The light of scope overexposure in interior irradiation light is easily produced, therefore, even with ultraviolet through visible ray inhale
Receive optical filter glass, for long-time use in the case of, can also produce deterioration (absorption in ultraviolet ray range), so as to easy
Cause the reduction of the light transmittance in ultraviolet ray range.
In this condition, it is an object of the present invention to provide a kind of new ultraviolet passes through visible absorption glass
And the ultraviolet being made up of the glass passes through visible absorption optical filter, its while carrying capacity of environment is reduced, make 350～
The light transmittance of the irradiation light in 370nm wave-length coverages is optionally improved, and suppresses the deterioration caused by overexposure.
To achieve these goals, the present inventor is through conscientiously studying, find using substantially do not include Pb, As, Cd and
Cr, but include 0.1～2 mass %, NiO of CoO, 1～5 mass %, TiO20～1 mass %, Nb2O50.1～10 matter
Amount %, and make the TiO2And Nb2O5Total content ratio is that the ultraviolet of 0.1～10 mass % passes through visible absorption glass,
Above-mentioned technical task can be solved, the present invention is completed based on the discovery.
That is, the present invention is provided：
(1) a kind of ultraviolet passes through visible absorption glass, substantially not comprising Pb, As, Cd and Cr, but includes CoO
0.1～2 mass %, NiO, 1～5 mass %, TiO20～1 mass %, Nb2O50.1～10 mass %, and make the TiO2And
Nb2O5Total content ratio is 0.1～10 mass %,
(2) ultraviolet described in above-mentioned (1) passes through visible absorption glass, relative to the TiO2And Nb2O5Total contain
It is proportional, TiO2Content ratio (TiO2/(TiO2+Nb2O5)) for 0～0.5,
(3) ultraviolet described in above-mentioned (1) or (2) passes through visible absorption glass, also includes：
SiO250～70 mass %,
B2O30～5 mass %,
Al2O30～5 mass %,
Na25～20 mass % of O,
K20～10 mass % of O,
0～15 mass % of CaO,
0～5 mass % of ZnO,
0～15 mass % of BaO,

(4) ultraviolet in above-mentioned (1) to (3) described in any one passes through visible absorption glass, with thickness 3mm's
The state of tabular, from the light source in wavelength 365nm with maximum radiant intensity with 500mWcm-2Radiant intensity irradiation include
It is during the irradiation light of ultraviolet light and visible ray, saturating in 350～370nm wave-length coverages of the irradiation start time of the irradiation light
The maximum of light rate is more than 75%,
(5) ultraviolet described in above-mentioned (4) passes through visible absorption glass, with the state of the tabular of thickness 3mm, from
Wavelength 365nm has the light source of maximum radiant intensity with 500mW/cm-2Radiant intensity irradiation comprising ultraviolet light and visible ray
Irradiation light when, the irradiation light irradiation start time 200～290nm wave-length coverage in light transmittance and 410～
Light transmittance in 690nm wave-length coverages is less than 1%,
(6) ultraviolet in above-mentioned (1) to (5) described in any one passes through visible absorption glass, with thickness 3mm's
In the state of tabular, from the light source in wavelength 365nm with maximum radiant intensity with 500mW/cm-2Radiant intensity will be comprising purple
During the irradiation light irradiation 100 hours of outer light and visible ray, it is more than 90% by the sustainment rate that following formulas (I) are represented,
(B/A)×100 (I)
Wherein, A is the maximum of the light transmittance in 350～370nm wave-length coverages of the irradiation start time of the irradiation light
Value (%), B is the printing opacity in 350～370nm wave-length coverages at the moment for beginning to pass through 100 hours from the irradiation of the irradiation light
The maximum (%) of rate,
(7) a kind of ultraviolet passes through visible absorption optical filter, ultraviolet by described in any one in above-mentioned (1) to (6)
Line is constituted through visible absorption glass.
The effect of invention:
According to the present invention it is possible to provide a kind of ultraviolet through visible absorption glass, which is reducing the same of carrying capacity of environment
When, the light transmittance of the irradiation light in 350～370nm wave-length coverages is optionally improved, suppress by overexposure cause it is bad
Change, and it is possible to provide a kind of ultraviolet being made up of the glass through visible absorption optical filter.
