They also can provide larger sizes and unique passbands upon request.\u003c\/p\u003e","brand":"Chroma","offers":[{"title":"1.25\" Round Mounted \/ 8nm","offer_id":44967250723101,"sku":"CT-27102-1.25M","price":1085.0,"currency_code":"CAD","in_stock":true},{"title":"1.25\" Round Mounted \/ 5nm","offer_id":44967250755869,"sku":"CT-HA5LRGB-1.25M","price":1344.0,"currency_code":"CAD","in_stock":true},{"title":"1.25\" Round Mounted \/ 3nm","offer_id":44967250788637,"sku":"CT-HA3LRGB-1.25M","price":1505.0,"currency_code":"CAD","in_stock":true},{"title":"31mm Round Unmounted \/ 8nm","offer_id":44967250821405,"sku":"CT-27102-31D","price":1085.0,"currency_code":"CAD","in_stock":true},{"title":"31mm Round Unmounted \/ 5nm","offer_id":44967250854173,"sku":"CT-HA5LRGB-31D","price":1344.0,"currency_code":"CAD","in_stock":true},{"title":"31mm Round Unmounted \/ 3nm","offer_id":44967250886941,"sku":"CT-HA3LRGB-31D","price":1505.0,"currency_code":"CAD","in_stock":true},{"title":"36mm Round Unmounted \/ 8nm","offer_id":44967250919709,"sku":"CT-27102-36D","price":1617.0,"currency_code":"CAD","in_stock":true},{"title":"36mm Round Unmounted \/ 5nm","offer_id":44967250952477,"sku":"CT-HA5LRGB-36D","price":1988.0,"currency_code":"CAD","in_stock":true},{"title":"36mm Round Unmounted \/ 3nm","offer_id":44967250985245,"sku":"CT-HA3LRGB-36D","price":2205.0,"currency_code":"CAD","in_stock":true},{"title":"2\" Round Mounted \/ 8nm","offer_id":44967251018013,"sku":"CT-27102-2M","price":3822.0,"currency_code":"CAD","in_stock":true},{"title":"2\" Round Mounted \/ 5nm","offer_id":44967251050781,"sku":"CT-HA5LRGB-2M","price":4025.0,"currency_code":"CAD","in_stock":true},{"title":"2\" Round Mounted \/ 3nm","offer_id":44967251083549,"sku":"CT-HA3LRGB-2M","price":4480.0,"currency_code":"CAD","in_stock":true},{"title":"50mm Round Unmounted \/ 8nm","offer_id":44967251116317,"sku":"CT-27102-50D","price":3472.0,"currency_code":"CAD","in_stock":true},{"title":"50mm Round Unmounted \/ 5nm","offer_id":44967251149085,"sku":"CT-HA5LRGB-50D","price":3675.0,"currency_code":"CAD","in_stock":true},{"title":"50mm Round Unmounted \/ 3nm","offer_id":44967251181853,"sku":"CT-HA3LRGB-50D","price":4130.0,"currency_code":"CAD","in_stock":true},{"title":"50x50mm Square Unmounted \/ 8nm","offer_id":44967251214621,"sku":"CT-27102-50X50","price":3626.0,"currency_code":"CAD","in_stock":true},{"title":"50x50mm Square Unmounted \/ 5nm","offer_id":44967251247389,"sku":"CT-HA5LRGB-50X50","price":4452.0,"currency_code":"CAD","in_stock":true},{"title":"50x50mm Square Unmounted \/ 3nm","offer_id":44967251280157,"sku":"CT-HA3LRGB-50X50","price":4690.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/products\/Transmission-Curve-of-Chroma-HaLRGB-Filters__04231.1596071532.1280.1280.jpg?v=1684339530"}],"url":"https:\/\/davidastro.com\/collections\/chroma-lrgb-filters.oembed","provider":"David Astro","version":"1.0","type":"link"}
