What is interesting about the image is that it shows a Carthusian nun, but wearing a stole and maniple -- the latter worn on the right arm instead of the left. The Catholic Encyclopedia sets the context:
"The Carthusian nuns have retained the privilege of the consecration of virgins, which they have inherited from the nuns of Prébayon. The consecration, which is given four years after the vows are taken, can only be conferred by the diocesan. The rite differs but slightly from that given in the "Pontifical". The nun is invested with a crown, ring, stole and maniple, the last being worn on the right arm. These ornaments the nun only wears again on the day of her monastic jubilee, and after her death on her bier. It is a consecrated nun who sings the Epistle at the conventual Mass, though without wearing the maniple."
Since we are on the topic, I will likewise again share these images from the Carthusian liturgy. (More may be found on NLM from previous years. Please use the search feature to find more.)
Finally, for those of you who would like to see more of the Carthusian liturgical texts (and I seem to be receiving a number of such inquiries recently), you have various options open to you. The current Carthusian liturgical texts may be found on the website of the Carthusian Order.
As for the liturgical books from prior to the reform, an older edition of the breviary may be found here and the missal may be found by way of Google Books:
